Thread: BZT - A Poor Quality Machine
A short video could tell us a lot. This machine so so simple that there is not much that can go wrong.
Is the current limit of the driver maybe set to low so it trips and stalls the stepper momentarily?
And returning it ... you still have to pay the expensive shipping to Germany and back , It might be cheaper to hire / ask someone local to take a quick look.
If you find the defective item they will probably send you a new one free of charge.

No we only ran one program making holes and only one person has operated. Dedicated PC etc
Dropbox video loads very slow, uploading to Mega.co.nz or youtube might be a better idea.
30 minutes download for a one minute video is just ridiculous.
Upload to Youtube is hours.
Ok to help properly we need all the info regards settings.
So take clear pics of the drives and there Dip switches. Need screen shots of the settings in the control software.
Can't see it being a wiring problem but if can take clear pics then do so.
This will most likely be a setup issue. Normally with systems like this with a motion control card they either work or they don't and it's rarely a faulty board that causes problems like this with 99.9% of the time it's either a setup or wiring issue.
Same goes for the drives and the Motors. They are simple devices which just work or don't. If they turn on then again 99.9% time they just need setting up correctly.
Setup is every thing with steppers and it doesn't take much to overtune them and make them stall. Some times they work perfectly fine at one setting but won't work at all with another.
Resonance can severly affect them and cause issues. For instance you trying them motors on the bench doesn't mean they will do the same on the machine.?
I've seen resonance cripple machines with very similair stalling motors etc at low speeds and by just changing the micro stepping which shifts the resonant frequency to another place they will work perfectly fine and give 2 or 3 times the speed.!!
It will 99% turnout to be something like this or a Wiring issues.!
