Hi
I have this problem that the Z-axis is not working correctly on my Xenetech 1625. It is not lifting between letters. (Specifically If I try to engrave with cutter up, it stays up, then if I put it on auto then it goes down a few thousands, with each up and down it just goes further down until it hits the table (or material!) but does not go up, also goes to home while dragging through the material)
Also making a huge noise when hitting "mechanical home" or "cancel", only correctly going home by manually lifting the spindle, also sometimes the green light flashes on the pendant and only resumes when spindle is correctly at home.
I have swapped all the cables, pendant, drivers in MPU , tested prox sensor etc. with the same result.
That leaves only one option, the Z stepper motor?, the details on the label only reveals that it is 1.8" (presume thats the size?) and 2.8A ???., the other info brings no results on Google.
Firstly can anyone advise what the problem could be apart from the Z-stepper?
Second can anyone advise the type of motor it is, what I need to specify when looking for a replacement. I am in the UK, so I am looking to purchase it domestically rather than going to Xenetech, (presume it would be cheaper also!). Or better still a model number & mfg./brand.
I have a similar motor but smaller on my Star 912, can I try that, temporarily?, could the power be different and blow it?
Thanks for any help,
