Chris, thanks for the effort put into the video. As a new Prusa MK3s owner (gift) I appreciate this video. Also, being a retired engineer i was somewhat disappointed at Prusa for (in my opinion) false advertising. The MK3 does not have true auto bed leveling by any stretch of the imagination. Never the less, it is what it is. Having much experience with metric nylon lock nuts I am a little skeptical that they will hold up to the bed temps and not 'go soft' and loosen. I will definitely follow this video but being an engineer I will have to set an 'OK' point on the height readings prior to adjusting or I will chase the elusive '0' all day.

Using the Super Pinda to do all these measurements is all well and good but I have to keep in mind that the firmware gets the same data from the same source, the Super Pinda and can and does handle these small inconsistencies on the bed when setting up the print cycle. Also on my Prusa the screws remain nice and tight and won't drift due to micro vibrations. I'm glad you did this and not me. Saved me a lot of trouble.

I think the biggest advantage for this mod is if you regularly print large two part models that are glued bed-side to bed-side. The mesh leveling is really good for correcting for a bed warped like at your start and make the first layer a consistent thickness (and therefore a consistent squish). But the situation like I describe will greatly enhance any deviations from a flat plain.

Heah Chris I just got a Prusa and yes my bed is off. I like adj beds and I have that on all my printers. I wanted to mention an observation. This method we are relying on only the 3mm threads in the alum bed support to keep the bed adjustment. Not sure I like that. I wonder what you think about the method I use for my Tevo Little monsters developed by Tim Fahlbusch. We use thick neoprene washers in place of the stand offs that are stock. We manually get all the bolts as even as we can then probe and do the first layer and get it like we want it by adjusting the bolts. This way we are locking things down by squeezing the washers that will keep a constant pressure not allowing any movement regardless of temp. The washers are high heat so heating them has no ill effect. The method you have shown us could be affected by heating and cooling since the only thing maintaining the adjustment is the 3mm threads in the lower plate. I am not a techie so I ask your opinion. What do you think? You have done this a month or so ago how has it worked out? I guess springs could also be used that would take the place of our neoprene washers.

When mounting the bed back on, I don't like fiddling with the standoff. So to start I turn all 9 screws the wrong way so I can hear the thread click when it jumps over the thread in the hole. Then I turn all 9 screws in one turn at a time, starting with the center one. As soon as this one is tight on the standoff, all others are at the right height too. Also it is one of the few times where I do like to use the angled Allen keys, because it is easier to do exactly one turn..

Hey Chris, Ty for the video but you have to do a bit more calibration at the end to see 'perfect' consistency and materially accurate parts. They nylock nut mod is definitely a plus, overall with overall consistency and sticking of the first layers. I also found it really helped getting my Z offset perfect and helped my clone machine just pump out ABS parts. Try calibrating the filament and following that teachingtech calibration web page. I'm getting a difference of about +/- .01 on about all my parts after all that on my original prusa and prusa clone I sourced.

I'm trying to print 2 colors on the same layer using one extruder on a Prusa i3mk3s. I don't want my printer to do bed leveling before I start printing the 2nd color. How do I turn bed leveling off for that 2nd color? Thanks for all your great videos!
@ChrisRiley9 ай бұрын
Thank you! I think the easiest way is to just alter the Gcode manually. Use Prusa slicer to find the spot in the print where you want to switch to the second color, then just type an M600 at that spot and run it. It will stop and ask for the second color.

@29:09 there is some measuring of the results. And it is called as being inconclusive. Well, how is that possible. Your values worsen for 50% of the measurement. 25%does not change at all. And the improvement gained on the other 25% is probably due to measuring inconstancy or biased measurement. The situation after the bed operation is worse than the situation before. 1.16 stays the same 1,13 becomes 1,12 1,18 becomes 1,19 1,15 becomes 1,18

I just purchased a Prusa i3 MK3S+ and are pretty happy with it, but the bed is not that flash as far as being flat, always wonder why companies dont put a thich sheed of alloy on as a bed, my guess is they are trying to keep it light, great printer though

@ChrisRiley2 жыл бұрын
So the firmware has a limit of difference that it will tolerate. When it goes over the amount it will try to level the gantry again. So you probably have a low/high spot that is a little too far out. Finding it might be a pain. Move the nozzle around on the bed and check it with a piece of paper, see if you can locate it.

How about the silicone tubing method? Instead of nylock, you use silicone tube, preferably OD-8mm x ID-3mm. I found the tube on Amazon... It sounds easier than using nuts, but it's it as good long term?

@@ChrisRiley I haven't touched my Prusa's, but did replace the springs on my Ender 3 with the silicone tube. BTW - you need 4mm ID. I ended up using a drill and 4mm bit to bore it out. It works nice, except I cut mine a little short. It compresses more than I thought. I'm going to redo it and increase the size by 3-4mm each....

Hi Chris , thanks for the informative video. I've been having the leveling problem for years on my mk3 that I've stopped trying. My question is if I use a nylon washer will it loose it form cause of the heat from the heatbed & wounding up adjusting the screws more frequent? Would it be better by using a metal/stainless steel washer?
@ChrisRiley3 жыл бұрын
Those washers and nuts should be good up to 220c. I guess there is another method out there now where they use silicone tube? There is a link to it here in the comments.
