The saying we have on another group is if there aren't pictures it didn't happen. I hand held the camera so depth of field is out a little on the 10-32 screw head and the macro lens is bad for depth of field as it is. Short G-Code 200 RPM tapping into really soft aluminium trimmed off an old

If you have a standard off the shelf FFF/FDM or SLA/DLP/mSLA printer then you are pretty much stuck with the limited slicer options. Most phone home or for  SLA/DLP/mSLA only output a proprietary format. I have a printer controller running nanDLP that we have isolated on the network. The

Hi Andy, The system currently uses PWM to a cheap (not the most linear) 0V-10V converter.Which means the PWM values for requested RPM at 100 should different than the requested PWM for RPM at 1500. All because originally the BIT file I was using for the 7i92H did not have an extra
