Re: Dubstar_04 - 40w Chinese Laser DSP Conversion
Hi John,
I am willing to try anything at this moment in time. I just can't understand why it's doing this.
I have built a number of CNC machines before and this problem is almost always caused by drawing too many amps from the Stepper drivers causing it to miss steps.
I have tried upping the Amp rating on the drivers. I might try going to 1.05 amps on the X axis and if that doesn't work i might try replacing the driver.
Any other ideas?
Thanks,
Dan

Is it possible that the pulley could be slipping?
If i could remove any chance of the problem being a mechanical one i can move on to look at other things.
I would think it doubtful if its a belt slipping especially at the low speeds you tried also a slipping belt would give random results (or at least a worst effect than you are getting ie slipping at each end of the axis) and a belt with teeth missing would surely cause every cut to step out of align where X meets Y ?

SUCCESS!!!!
I changed the pulse edge from falling edge to rising edge and it seems to be working.
I tested exactly the same file and it looks perfectly aligned!!
Thanks to everyone for your advice.

Here are a few pictures of the design being cut after changing the setting:
You can see the engraving and cutting is now aligned.
