Build Your Own SLA/SLS

Hey guys,

after building my own SLA Printer, everything works fine except the tilt function.

The z-axis works fine, and the x-axis, which is used for the tilt doesn't. You can here some noise from the stepper but nothing moves.

I tested my Ramps and the stepperdriver with RepetierHost and everything worked. So the Ramps and the stepperdrivers are working and i didn't changed the voltage of the stepperdriver after i had set them up.
I think it must be a problem in the firmware but i don't know where. I've controlled the axis steps per unit and the direction and so.

Who can help me???

Check the feedrate of your tilt axis. Assuming that the tilt is the x axis:
G1 X10 F100
This will move your X Axis 10 units at a feedrate of 100. I think the default X/Y feedrate in CW is around 3000 because it can also be used for FDM printing.

Thanks for the fast answer,

i've changed the setting in the machine control to x/y rate 10 and in the machine config the x feedrate to 100. Is it correct?

Are the any changes in the arduino firmware?

I've tested these settings and it didn't work.

Have you tried Marlin with CW? If you've gotten Marlin working with Repetier, CW should work fine with it as well.

Now i've tried Sprinter in RepetierHost and the same problem. With Marlin the same. I don't know what to do.

It sounds like the stepper wants to move but it doesn't. I've checked the way of the stepper and there is nothing what stops the stepper.

I've test different kinds of configurations in the Arduino file but no changes.
I've tested the x-axis with the same settings like the z-axis, but the x-axis doesn't work.

Could it be that the Ramps is broken?
