Re: M2 Accuracy -- What's reasonable to expect?

The hope is you get it close enough that the firmware just rounds it to 192 steps.
Oh ok. I get it.

Re: M2 Accuracy -- What's reasonable to expect?

Fine, then use 0.1905328966954451 as the layer height.
I get your point, but how is 191.96 steps @ 0.1905 mm layer height easier to process than 201.54 steps @ 0.200 layer height?

Re: M2 Accuracy -- What's reasonable to expect?

it's more that the firmware won't care after a certain precision. i don't know what it is, but .1905 will be close enough
I'm still not seeing how (1007.70 steps/mm)(0.1905 mm) = 191.96 steps is an even number of steps that the printer can more easily process.

Re: M2 Accuracy -- What's reasonable to expect?

You need to use similar filaments when comparing look. CF looks amazing in general - there are a couple of screenshots of CF prints on the M2 and they look great. The CF print from the Markforged printer was just to show what a commercial desktop printer is capable of. Some users were suggesting th...

Re: M2 Accuracy -- What's reasonable to expect?

I must say, I'm jealous of the Flashforge results. My M2E is probably somewhere between your M2 and the Flashforge, but I'm still tuning things. To add insult to injury, the Flashforge cost $1k less and printed that cube at 80mm/s, twice the speed of the M2. If Makergear would add a proper blower-t...

Re: M2 Accuracy -- What's reasonable to expect?

1. I'm using Simplify 3D for the Makergear M2 Rev. E, Flashforge Creator Pro, and the Ultimaker 3, but Eiger.io (Markforged's proprietary cloud-based slicer) for the Markforged Mark II. 2. My M2 Rev.E's z-nut is black, not brass. I'm assuming this is the latest iteration of this z-nut for the M2? 3....

Re: M2 Accuracy -- What's reasonable to expect?

Thanks for all the great feedback Zemlin! I took your advice and printed four cubes at once. The lines are still there, but like the 0.100 mm (z-res) print I ran, there are more of them and they are closer together. I'm still waiting for Makergear support to get back to me on this problem. I am curr...

Re: Defective z-axis or PID needs calibration?

@ Zemlin (thanks for those photos!) IMHO, you are, to an extent, on a witch hunt, lighting your test parts so they look as bad as possible. Hahah. I used low angle lighting not because I want my prints to look bad, it's because I'm trying to show the issue more clearly. I have no idea if this is a h...

Re: Defective z-axis or PID needs calibration?

I did a little research before running PID autotune the first time. The effect of the cooling fan on the PID values was heavily debated. Also, if the effect was pronounced, that means the PID values would be completely wrong when you switch to a filament that doesn't require cooling (ie. ABS). To te...

Re: Defective z-axis or PID needs calibration?

No lines.jpg Lines.jpg I re-printed the same cube again, this time in Makergear PLA. The issue still shows up in the cube with infill. I sent Makergear the g-code I was using and they can't replicate the issue. The cubes need to be illuminated from the right angle to see the lines (see photos). I'm...
