I have a suggestion for your viewers I am sure you are aware of this, when measuring with the calipers the beam of the calipers need to be parallel with the stock you just cut. To prevent measuring a parallax. To do this I place the material on a flat surface and the points of the calipers on the flat surface this keeps the beam parallel. Great video Rich! I am head out to the shop to calibrate the kerf and then the actual cut. Thanks for mentioning that sequence!😁🛫

First off, great info, thank you very much from Trinidad and Tobago! I'm really enjoying my brand new Comgrow Z1 and completed the X,Y calibration perfectly (it was a tad off on both axes). Then I measured the squareness with my shop's machinist squares and found it to be a tad off also. Corner to corner diagonal measurements of the fame are fine, the table surface is flat (frame rests on a 26'" x 26" x 3/8" sheet of plate glass, and there are three little legs between the glass and bench), so I know its flat. Found the gantry to be out of square relative to the two blue supporting plates (~1.7mm over the full length of the gantry). my solution to that problem was to paper shim the interface between the front of the left gantry support (blue Plate) and the gantry bar using a thickness of four sheets of printer paper, this absolutely solved the problem. I now have a machine that tracks perfectly square and the x, y calibration is spot on. I've also added a Comgrow Lightburn Camera (camera module arrived defective, replacement on the way) and I also designed and made a pair of laser cut acrylic brackets for the Comgrow camera mount to provide overhead lighting for the bed. I will find somewhere to post the DXF file for those brackets, some pics of my rig and also an amazon link for the light bars I used. Very happy with this machine and thanks again for all the tips.

Hey Rich, just another thought on the topic. I have a CO2, so I can't speak about settings in a diode laser, but I'd bet setting a jump setting to move 100mm, then measure the two points from a pulse burn would be more accurate than making an actual cut, which would mostly remove the kerf offset variable. You could generate a grid along the X/Y to determine where you fall out of tolerance and your averages would be more reliable. Thanks again!

Rich, thanks as always. I just watched the video you did on Kerf (thanks again!) and posted a question that I'm repeating here on this more recent video - sorry for the duplication. I'm a beginner at this craft, but it seems like there is interaction between X- and Y-Axes Calibration and Kerf. If I'm correct, this calibration moves the cut line outside the desired dimensions so the inside of the cut line gives us the desired dimension of the cut square. Does Kerf do the same thing? Are these two adjustments cumulative? Is calibration of the axes more important than Kerf, unless you're doing something like puzzle pieces? And I imagine that the actual laser spot when focused has something to do with all this is well. I suspect the answer is test and test again and you've given great tools to do that with, but the interaction of these two settings is still a question for me. Thanks!
@TheLouisianaHobbyGuy Жыл бұрын
No Pat, this just gives you overall accurate dimensions, while the kerf offset changes the accuracy to add or reduce size for a better fit of joined cut pieces.

Rich, I wondered when you were going to make a video on this subject. So many people don't understand accumulative error. If you measure the belt pulleys they are not all the exact same diameter so every time they make a revolution the error gets larger. Try explaining this to folks in the 3D printing arena. They want to do everything but adjust the number of steps per millimeter on their stepper motors. Then I have people tell me that the machine uses a timing belt so the diameter of the sprocket pulley doesn't make any difference. Not so. Any given point on that belt has to travel the circumference of that pulley. And they are all not the same circumference. I have measured the diameter of my pulleys with a micrometer and they are not all the same. This is why the software writers go thru the trouble of writing this calibration feature into laser and 3D printer software, or anything that uses stepper motors. Of course another factor in the equation is how your curf offset is set when you do the test. Do you use no offset? Or do you do a complete offset to the outside? In opinion (and it is like you know what) we to calibrate for the movement of the center point of the laser. That way the head moves the exact distance we tell it to in our drawings, then use kerf offset to get the actual size after the burn. On blue diode lasers it will never be perfect because the laser dot is rectangular.
@TheLouisianaHobbyGuy Жыл бұрын
You got it Kris. This is a very controversial topic in the CNC world, and especially with the 3-D printers because there are so many "experts" with different opinions. I'm no expert, nor do I claim to be, but I know this works for me 🤪 I only use the kerf offset on inlays.
@TheFalconJetDriver Жыл бұрын
You mentioned blacklash I know what it is, and yes it is extremely important if you want repeatability. My question is where would I find this backlash offset? I am thinking they way you stated that this is in the software of the drivers for the stepper motors? And if so how could I find this? Or is it an arbitrary number that was plugged into lightburn that I need to fine tune? You videos are outstanding! Thank you for sharing your knowledge! 😁🛫
@TheLouisianaHobbyGuy Жыл бұрын
Backlash is a complete video of its own. Think belt climb instead when changing directions, since that's what hurts the precision. The faster you run a scan, the more likely your belts will climb on the timing gear and skip teeth in some cases.

@krproton Жыл бұрын
Thanks for your informative video(s) and taking the time to produce all your videos and explain. But I have a question: In this calibration video, don't you have to account for the kerf? Your machine cut your square 150mm x 150mm (within a couple thou), but now inside cuts will be oversize. In this example, the outer dimensions of your square were 150mm x 150mm, but now the inside will be oversize by twice the kerf. In other words, you've factored in outward offset. If I'm right (and I may not be), I think the correct way to do this would be to first find out the kerf, then cut your 150 x 150 square, measure, then subtract the kerf to find out the true value for the calibration. If, say, your kerf is .01" (let's call it .25mm), and if your square comes out to 149.75 x 149.75mm, then your calibration is perfect. In other words again, if you send a 150mm x 150mm square to the machine and the X and Y are calibrated perfectly, the machine will cut a square that measures 149.75mm x 149.75mm because you have to account for and subtract the kerf (or, actually, half the kerf from all sides).

@@TheLouisianaHobbyGuy Oh, okay, I get it. But what about when cutting something that the inside dimension needs to be correct? Would you then use offset?

Shouldn't the kerf width be factored in before entering the adjustment? What if it was the square hole was what I was after and the center square piece (the piece that you took your measurements on) was the waste piece in my project. I think that the machine should be calibrated to follow the center of the cut line (kerf) and if the project needs exact measurement then adjust for that in the kerf setting. Am I missing something? Great video BTW, I think you do an amazing job Rich and I have learned lots from you. :)

@briansmith7046 Жыл бұрын
Hey Rich, since you are doing your calibration without entering a kerf adjustment (or taking into consideration) would you actually be including your kerf into your calibration? Basically, the calibration is looking for a distance of 150 and you cut out the piece and say the finished actual cut size is 149.8. If you enter requested distance of 150 and actual distance of 149.8 you have included the missing kerf amount into your calibration? You have 1/2 kerf on the top, bottom, left and right sides of the actual cut out (kerf is half because you cut on the line meaning half of the kerf is inside cut and half is outside the cut), so if your kerf is .2 then the kerf offset should be half of the total kerf which would be .1 for each side? If that is accurate then would not 149.8 be the expected value for a calibration since I think calibration is looking for a distance from the middle of the laser line to the middle of the laser line rather than the designed size vs actual size?

Maybe I'm wrong, but this process should be a 1 & done procedure (I'll be checking mine soon as I get time). Coming from 3D printing, once the step distance (rotation distance in printing) is set, the calibration shouldn't need to be performed again unless the pulley is replaced or its diameter changes due to wear. Translating circular to linear motion doesn't care what you use be it a belt or string. The distance moved in X or Y is determined by the pulley diameter and number of steps commanded. Now, those pulleys have a manufacturing tolerance and for certain that needs to be baked into the settings using this calibration method. Also as you indicated, a 0.5mm error at 150mm (0.33%) multiplies as the part gets larger. As a % the value is small, but multiplied by 400mm or so (1.3mm error now) it will destroy the fit of mating pieces. A 0.125% error would yield a 0.5mm error at 400mm. If the belts are good, the rest of the system should be capable of this. If the laser setting is steps/mm & I did the math right, 80 steps/mm (from the value on your screen) is 0.0125mm/step.

Shouldn't you determine what your kerf is first and then take that into account when calibrating? As a hypothetical, at one extreme, imagine your kerf is 1mm (0.5mm off of the exact center line on each side), and you are calibrating for 10mm. If you get your machine dialed in exactly for a 10mm square (11mm center line to center line - 1mm kerf), and you scale that up to 1000mm, I would think you would end up with a 1099 mm square. 10mm + 1mm kerf = 11mm; 11mm * 100 = 1100mm; 1100mm - 1mm kerf = 1099mm At the other extreme, if you get it calibrated for exactly 1000mm with the same 1mm kerf, then you scale that down to 10mm, you would end up with a 9.01mm square. 1000mm + 1mm kerf = 1001; 1001mm / 100 = 10.01mm; 10.01mm - 1mm kerf = 9.01mm With exactly 1mm of kerf, I would think that you would want to cut a "10mm" square and get a measurement of 9mm, that way when you cut a 1000mm square, you will get 999mm, and then use the software to account for that kerf the same way a cnc router accounts for bit diameter. That way, you're accurate regardless of the size of the project.

@@TheLouisianaHobbyGuy I understand that, but I would think that you would want to calibrate it from the center of the cuts on both sides, not from the center of the cuts minus the kerf. If you only calibrate it from the finished cut, you're not getting a proper measurement, and that will affect your cuts on the other end of the scale. In my first example above, you would need to move the laser head 11m to make a 10mm square, which is 10% too far. If you wanted a 100mm square based off that calibration, you would move the laser head 110mm (100mm +10%), which would result in the wrong size square. Instead, you actually want to only move it 100mm plus the kerf offset. While you are still effectively moving the laser head 11mm to cut a 10mm square, it's how you go about it. Calibrating directly from the finished cut, you are telling your machine that 11mm is actually 10mm, which will throw off your measurements as you change the size. Conversely, you want to tell your machine to move 10mm and have it move 10mm, and have Lightburn (or whatever software) add in the kerf offset to make it move a total of 11mm, so when you change to a 100mm square, it only moves 100mm plus the kerf offset instead of 110mm
@petercarter4150 Жыл бұрын
The calibrate axis function in lightburn, your meant to measure how far the head moves on each axis not how big the cut is. The kerf offset should make it the right size not the calibration. Your method is easier but does add the kerf on to your measurements so the above user is right.

One more Question, if i calibrate the axis, is there not also the Kerf involved? Saying you calibrate the axis to your 150, the result should not be 150 but 150 minus the Kerf, or am i wrong?

Thank you for another awesome video! One thing I am confused about is how to account for the Kerf. My 150 x 150 mm test cut in 5 mm plywood came out symmetrical, but the square was too small. Once I did your kerf test from your other video, and adjusted the curve by 0.2 mm, I got a pretty perfect 150 x 150 mm square. I cut the same test piece out of 3 mm black acrylic, adjusted the curve by 0.1 mm, and also got a pretty perfectly sized 150 mm square. if I had calibrated my machine based on the wood square, I still wouldn’t have gotten the acrylic correctly. So would you say that if you get a symmetrical square, but the size is off, to just adjust the kerf, not the machine? Thanks a million!

So when doing this calibration, is the software only adjusting for the difference between axis, or is it going to change all dimensions? As in, if your 150mm box cut 149.05 due to a .1mm laser, would it then cut 150 after this calibration? Because I'd assume that would then cause issues with future kerf offsets. Long story short, should we be adding a kerf offset to the layer settings before cutting the test piece?
