I have read all posts near what I am experiencing but could not find a fix.
I print a calibration block of 30mm x30mm x 10mm (Z). The print looks very good and the X and Y dimensions are very close to 30mm (like 29.95mm) but I can’t get the block to get higher than 9.3-9.4mm. This is a 6-7% error on Z. I need to print engineering parts so this error is enormous.
The block sits on a 0.3mm base. After removing first layer, it gets to 0.25mm. I added the base in Solidworks so we are not in the case where the base’s layers are overlapping the block’s layers in CW. It really sits over it and total height is 10.25mm. The slicing seems right since I get 205 slices (10.25 mm).
I print at 50um (XY) and 50um Z. The slice thickness in CW and Kudo interface are both set to 50um, that’s for sure.
I use 3DSR engineering hard and added 0.5% black pigment in it to avoid light bleed in case it would affect the Z resolution. No change.
I tried many exposures from long to short (from 15 sec to 4 sec). No change. I use high lift height and low lift speed (10 to 12 mm/min) to make sure this is not the problem.
I measured the precision of the linear stage with my caliper and it seems to be fine.
The Z height showed on the interface while printing is fine. Ex: at layer 100, the height shows 5mm.
I don’t know what to do anymore. Any help would be greatly appreciated!
