Re: How to move CW stepper motors?

ok so the program is working have you adjusted the steps to match your machine configuration in the arduino code ? as instructed (PlatenStepsPerLayer) and set the switches on your stepper driver to match ( 16 microsteps) see this section in the arduino code: > adjust "PlatenStepsPerLayer" ...

Re: Z-Axis from Kickstarter

i'll guess that your exposure time , is too high
try lowering the exposure until it's just not curing then add 10- 15%
worth a try either way

Re: How to move CW stepper motors?

if you are 100% that you do not recieve "ok" when using the arduino terminal the problem is your arduino code is not uploaded or running correctly. this needs to be correct before you can move on to CW . check you are uploading the arduinocode correctly to the correct comport & board s...

Re: New LaserShark Based SLA Build

here is some more information on adjusting the 20k drivers , ive copy'd just about most of it to make sense i think . it does say to use a ilda test pattern from lasershark . or will have to see about probable producing a test pattern as gcode for example .so it can be used from CW is my suggestion ...

Re: Z-Axis from Kickstarter

yes i'd agree , but precision is additive , depending on what is driving it , steppers , servo's , let alone to the depths of the associated drivers also to be able to make an item to a given dimension you need equipment , 10 times more accurate so overall i'd doubt their claims (nicely) as your now...
