Topic: How do some printers achieve 20micron Z resolution?
Is it through micro stepping? If so, does micro stepping have good precision? And how does the extruder handle such high resolutions?

Re: How do some printers achieve 20micron Z resolution?
I have yet to see an FFF type printer claim to do this. Do you have link to one? I would like to check one out. I doubt microstepping would help much in the Z. It is usually used on the X and Y to make things more round and smoother at the cost of torque.
Printing since 2009 and still love it!

the top 2 claim 20 micron from wanhao, im not sure how good wanhao is though.

Wanhao is a copycat of CT'c there parts are identical as I buy parts from a Wanhao distributor for my CT'c. I can do .1 on my CT'c but not sure I could go smaller.

Re: How do some printers achieve 20micron Z resolution?
Most Z lead screws would be able to handle 20 micron theoretically; one of the more standard screws is 8mm x 1.25 pitch. With 1/16 micro stepping the resultant steps / mm would be 2560. 1mm / 2560 = .00039mm per step...so about 50 steps would give you 20 micron.
BUT, this assumes that the structural integrity of the entire Z platform can handle this accuracy...
Beside that 1/32 on the extruder motor coupled with a 0.9 Stepper Motor and a HobGoblin might give the extrusion control necessary.
Bear in mind this is 5 TIMES a smaller layer height than .1...even smaller prints could take hours! I think I'll stick with .1 when necessary...

I am trying .02 now on my CT'c which is the same as a Wanhao. I'll let you know how it comes out as a 20mm cal cube is going to take many hours. According to Simplify3d the projected time for a .02 layer 20mm cal cube is 10 hours and 20 minutes. Thats with a 20% infill.

Re: How do some printers achieve 20micron Z resolution?
I printed a companion cube on our R-530 printer at .05mm and .14mm layer heights. The difference between the two is really noticeable but it did take much longer. I can't imagine ever needing to reduce the layer height below .1 other then to see if its possible.
