Thanks! I try to teach the way I need to learn things... slowly and with lots of pictures!

Be sure to catch the Frankenlabs series... I'll be adding a PROBE video shortly.

+Bruce Golling When you get it running... be sure to let me know... post a video if you can!

Awesome! Be sure to watch the Frankenlab series as I build and program a machine from scratch.

+David Stevens (davro) I've been busy... but I should have some new CNC videos soon.

+askjerry Cool stuff, I have managed to setup a 3 axis milling machine! Next is the 2 axis lathe, should be simple :)

+David Stevens (davro) Just remember that the lathe needs an index and phase input to calculate rotation for the threading routines. I have a lathe that I want to set up as well... may be awhile until I am able to get to that project unfortunately.

jrcrosier13 Go to my askjerry.info page and email me. We can look into it further.

Im trying to think what to do next. Glad I was helpful. :- )

@@Askjerry i think you can make complete tutorial about home limit switch setup, touch probe inside hole and outside block. And how to setup Closed Loop using servo or Hybrid stepper. I'm new in Linux CNC, before i'm using Mach3 with Open Loop, now i want using Linux, because i'm hear from someone Linux CNC able to control Closed Loop System. And can save last position if have problem with power.

@@isulistiawan Have you looked at my Frankenlab playlist? I cover the probe, limit switches, setting the home positions, and I even made a complete probe plug-in that you can install... free. Saving last position is easy if you use the G54 home... all covered in my Frankenlab series. kzfaq.info/sun/PLa_L8q5vezBOkzP_yOKBXPB8zKn-iWCsX

askjerry So if you want to microstep at 12,000 for example it would be 60?

Some clarification on the tpi. If you have 2 it’s the same as 5? So what if 5 is input? 10?

@@glennedward2201 When configuring LinuxCNC, there is the microstepping setting, number of threads per inch/mm. And a ratio of stepper to shaft in the event you have a belt system for example. Sometimes I just cheat... I tell it to move 1mm and it moves exactly 3mm... I may just go in and multiply the number of steps by 1/3... Or... I may just tell it the ratio is 3:1 and let it adjust. In the end... The INI file gets a scale number that sets how it performs. Once configured... I NEVER go back to STEPCONFIG. I manually tweak the file to get what I need. There is a guy in Egypt (hello Trucker!) Who built a machine from scraps found at the junkyard... No telling what the exact ratio or scale was on those parts! So we approximated until it was running smoothly... And somewhat close... Then we figured the machine could move 4-feet. We told it to move 40 inches... It moved 40.575 inches or so. The scale was like 6.8750... So we changed it to 6.8... It went 39.7 inches... Then 6.5... Etc... Until we hit 40 exactly. Then we told it to go 48 inches... It went 48.05 inches.... Made from junk. So don't stress over it... Get it as close as you can mathematically... Then dial it in as needed. And watch setting microstepping too high... Every step up requires more pulses... Your computer can only make so many per second... So it gets slower. You need to find the balance between speed and accuracy. Math will tell you that you have achieved 0.000001 inch... You haven't. With slop, backlash, wear... Maybe 0.0005... With good ballscrews. Frankenlab has like 0.025mm or so... It cuts plastic and wood.... So i run a bit faster than if I attempted to get that 0.005mm setting... In my case... Close enough for project boxes and training.

+petsatcom I'm not really sure... I have not done that type of setup. But, if you take a look at the LinuxCNC Forum... I'm pretty sure you will find an answer. forum.linuxcnc.org/forum/index

A parallel port has 5 inputs. For my set up, I added another PCI parallel port. this gave me an additional 5 inputs and another set of outputs. You could instead use a MESA card... with 24 or so inputs... but I have not installed one yet.

+askjerry Thanks Jerry, you are the man

+askjerry And I guess we can assign functions to these Pins, that is when a G-Code program has a line that basically says MOVE tool 6 into position, we can send a signal to an output PIN that make the turret move to the CMD position. Thanks!

+petsatcom Sort of... the pin goes high (or low) and some G-code is called... same pin no matter what tool... you pass a variable to the controller that does the job. Check the LinuxCNC forum for details.

I have the Monster running on a Stainsmart connected to a parallel port... It runs fine.

It does have backlash compensation... linuxcnc.org/docs/2.6/html/config/ini_config.html I am doing even better than a Part 2... i am making an entire video series... building a milling machine from scratch... and then going through how to program a custom panel. kzfaq.info/sun/PLa_L8q5vezBOkzP_yOKBXPB8zKn-iWCsX

Thanks for the response yes I seen parts 1-5 of franken looking forward to the software side videos. I'll keep an eye out. Thanks again. Mike

but linux cnc has the impressive outlook , unlike the grbl shields linux cnc // It is awesome

RULE ONE: When you get something that works... even if not completely... BACK IT UP! Frankenlab is on version 6 now... and I have versions 1 to 5 backed up... in case I need to look back to see what went wrong.

Unfortunately, I have not made this type of system. A good place to start would be here: forum.linuxcnc.org/forum

That is the exact board I use on both of my CNC machines.

Melissa Oliva Not a silly question! The breakout board takes the signals from the parallel port and gives you nice terminal strips to attach to... it also has a relay for spindle switching, etc. But that is all it does. To operate a stepper motor, you must take 3 signals... enable, step, and direction then convert them to the electrical power needed to operate the coils inside the stepper. This is what the driver does... it DRIVES the power and control to ONE stepper motor. So yes... one driver per stepper. There is an exception... Frankenlab uses TWO steppers to rub the 6-axis... but BOTH steppers are always doing the SAME thing... and the driver I chose had enough current to safely operate both. As always... you can get my email from my web page should you need more help. (If I have the time of course.)

I've use these... a bit overkill for what you want... but cheap. www.banggood.com/TB6600-4A-CNC-32-Segments-42V-425786-Stepper-Motor-Driver-Controller-p-1093437.html As for the breakout board... I like the Stainsmart. www.amazon.com/SainSmart-Breakout-Board-Stepper-Driver/dp/B0093Y897A

Greg Not sure why you would need 4-axis to wind filiment... I guess I would need to see the configuration. As for programming... you could step through the first one... recording the steps... then just run the code as needed.

Hi Thanks for responding so quickly. I bought a 4 axis winder from these guys www.xwinder.com/filament-winders/. I'm having trouble with it and the support is not really there, Thinking about making it less of a black box.greg

Laptops can sometimes run too slow... but if you want, you can put the ISO on a thumb drive and experiment with it... if it looks good, then install and start the setup. Run the speed test and see what kind of number you get... 25000 or so is fine... 50000 or so will probably get an error n startup, but may still work. If you are not using the laptop anyway... install the ISO and give it a try. If it doesn't work, it will have Libre office, so you can still use it for documents, spreadsheets, Gimp and Inkscape will let you do graphics... so it's a win either way,

Melissa Oliva STEPCONFIG doesn't care... it creates the INI and HAL files and makes a desktop launcher. It also only configures for 4-axis. If you want to do a hexapod... 6-axis... that will need to be manually configured. If you have an INI file, use the CNC dropdown to create a launcher and start it. Google the LinuxCNC Forum for more info.

Okay I see. Do you have any videos where you configured a hexapod or anything more than 4 axis? Thank you

Unfortunately I do not have a configuration like that, however there are discussions on the LinuxCNC forum which can be found here: forum.linuxcnc.org I did find this section... aparently there are samples covering this in the samples section. forum.linuxcnc.org/38-general-linuxcnc-questions/31069-using-linux-cnc-for-6-dof-stewart-platform#75723

I have not... I haven't had the chance to work on one yet.

The configuration determines if one axis at a time will move or if all will move at once. Typically it is configured so that the machine will do Z, then Z, then Y. Have you configured the switches so that P12 is the Z axis, then P11 is the Y axis, and lastly O10 is the Y axis. The home switch must match the axis specified. You also must configure the switch so that the closure of the switch indicates a home condition. If this is reversed, then the machine will assume the home switch is depressed and move in the opposite direction looking for a home indication. I recommend that you activate the machine but do not home it... then next to FILE you will see MACHINE, hover over that and click VIEW HAL CONFIGURATION to bring up the next screen. Click on the tab WATCH as we will select certain pins to evaluate. Click on PINS Look for AXIS 0 and scroll to select HOME-SW-IN and select it to add it to the WATCH tab. (X-Axis) Look for AXIS 1 and scroll to select HOME-SW-IN and select it to add it to the WATCH tab. (Y-Axis) Look for AXIS 2 and scroll to select HOME-SW-IN and select it to add it to the WATCH tab. (Z-Axis) All three should be RED (not active) at this time. Click the Z-Axis Home switch, does one of the red dots turn yellow? If not, you have a wire or configuration problem. If yes, verify that it is the correct switch. Once this is corrected it should function normally.

Currently (July 2018) all my machines and those for people I've helped have all been just a parallel port. My Monster Mill is using two parallel ports and two breakout boards. I just now started working with a MESA 6i25 and 7i76D plug-n-go set that will be used to convert the Monster Mill into a 5-axis. (And a whole new video series/playlist.) Probably have the first videos on that out starting maybe September. (Shhhh... secret!)

The CNC machines are set up in Linux Debian... www.debian.org/ The machine I use to make my video is Windows 7.

Ok... it sounds like you are saying that you have a Mach3 breakout board, but want to configure LinuxCNC to use this board... is that correct? If so... we need to write down the way the pins are configured on that board... then match those settings in the STEPCONFIG. Once that's done... it's a matter of calibrating the machine. When I do a Google search for the Mach3 board... i am seeing more than one configuration. Go to my web page askjerry.onfo and get my email address. Email me and I will assist you.

No Mentor I am a nubie . and am stuck with wiring it up. I have a home made cnc With 3 axis with displacements of 30 cm X , Y and 20 cm for Z . I have been runnung it with grbl and cnc v3 ardunio shield now i have the set of Mach3 breakout board with 3 stepper drivers . But have no clue how to wire it up I am sending you an email with pictures Hopefully You will guide me to be a C N C upgrade, Once all wired then will go one level up to configure the machine with software .

Yes, I will be glad to help you.

I do not know... you would need to check the LinuxCNC forum

Email me and I'll work with you to figure it out. I travel a bit... so it may take a couple of days. I'm sure we can get your system running. My email can be found at my askjerry.info site.

rafi saifuddin It evolved into an entire tutorial series... Frankenlab CNC: kzfaq.info/sun/PLa_L8q5vezBOkzP_yOKBXPB8zKn-iWCsX

thanks for quick reply,

There is a lot of discussion on this topic here...forum.linuxcnc.org/9-installing-linuxcnc/30302-linuxcnc-on-raspberry

sorry, I mean how to configure linuxCNC (in raspberry: machinekit) GPIO pin connection between raspberry pi and motor driver without convert gpio pin to serial port

@@JanSebastian213 Honestly I have no idea. The best thing to do is get on the LinuxCNC forum and start reading about Machinekit and how it functions.

ok, thank you very much

+mortrem76 The PC is the controller... the LinuxCNC makes all the drive signals and sends them out the LPT port to the motor drivers. I am building a small 1/2 meter cubed machine to train people with... when done... I'll have a whole series on setting it up and experimenting!

I cannot believe it has been 10 months already! I still have to do it! I am doing a series on the Arduino right now, part 5 of 10... then I am also building my new Frankenlabs platform... a small CNC machine built exclusively to teach CNC setup, operation, pyVCP panel configuration, and if I can learn it... Glade configuration. This video may get re-branded as Frankenlabs part 1... and I'll pull the existing two into it as Part 2 and 3... dunno. Been working 12 hour days the last month... I'll check out the screen capture... thanks!

Id like to see an explanation of the various screen options as well as how you can add items to the 'side box you suggested to install.

Oh and just accept the default options for the screen capture and you cant go wrong. (Works in Linux only) (Its a largely undiscovered gem.)

THANKS. I appreciate that... I'll see if I can get it running this weekend. Possibly do an introduction to the pyVCP. Dunno... see how the weekend goes.

That is either a GLADE or a pyVCP panel... yeah... I need to do that.
