Re: Wrapping 4th axel does not work - HELP

And is it even possible to user ARC-command G02/G03 when engraving on a rotating workpiece. Isn´t G02/G03 movements both x and y? And then y has to stand still and the axel is instead rotating.

My knowledge in this matter is really limited but I am willing to learn :)

Re: Wrapping 4th axel does not work - HELP

Regarding G02/G03.

I think that the software Vcarve does the choice not to use G02/G03 when making cirkels on rotating axels. I let the job be flattened and then it used G02/G03.

Or is it really only depending on the postprocessor-file?

Re: Wrapping 4th axel does not work - HELP

Thanks both for your help. I will talk to WinPC-NC and ask if it can be a rounding error.

I will give full feedback as soon that I will have some facts

Best regards

Re: Wrapping 4th axel does not work - HELP

Hello again. I have done a test and really tried to logg everything. If someone has a chance to take a look and give me some hints on what can be wrong. Is it really a mechanical problem with the 4th axel? I have tried to get in contact with the dealer of the motor but so far no answer. Flat jobs is...

Re: Wrapping 4th axel does not work - HELP

Hi TReischl I have tried with very slow speed. Feedrate 0,02 in/sec. And there is no change :-( I will try getting some answers from GoCNC in Germany, if they have any experience with there 4th axel and motor. Its control-card sits on there main-controlboard for the CNC. The mainboard has a setting ...

Re: Wrapping 4th axel does not work - HELP

Hi TReischl I am not trying to blame vectric, I am trying to find out where the problem can be. I am just now directing questions to GOCNC who I bought the machine from. Also WINPC-NC that is controlling the stearing of the machine from the G-code from Vectrics postscript. And ofcourse, reading G-co...

Re: Wrapping 4th axel does not work - HELP

Hello again. I made a discover! If In Vectric Desktop sets the zeropoint for X and Y different, the output is completely different. IMG_1023.JPG If I set the XY Datum position as the Picture shows, the outcome is very bad. Like the lower engraving in the Picture added to this mail. You can see that ...

Re: Wrapping 4th axel does not work - HELP

Is this something correctable in software or is it mechanical and can not be fixed?

It looks like the smaller circular movements the greater loss. If I only engrave squares, they are fine but if I put some figure together with them, all starts to be missplaced.

Re: Wrapping 4th axel does not work - HELP

One more thing. When I do jobs on a flat surface, and restart a job, the milling/engraving is very exact and hits the same track´on the working piece. But when I do the same with a rotating axel, the restarted job never hits the same track again. So If I do 4 exactly same engravings, they will all b...

Re: Wrapping 4th axel does not work - HELP

IMG_1018.JPG IMG_1019.JPG IMG_1017.JPG This is picture of the engraving in ´Vectriv Desktop, both the drawing and the preview. And then the engraving on a wooden stick. This example can be much worse. For instance a circle can more look like an "e". And a star can have one leg totally miss-engraved...

Re: Wrapping 4th axel does not work - HELP

yes, one revolution on the steppmotor is 360 deg but the gearbox has a 2.5x exchange so that the axel does not move more than 144 deg. So 1000 steps is one revolution on the axel and 2.5x360 deg on the stepmotor

Re: Wrapping 4th axel does not work - HELP

I have both used the postscript that comes with Vcarve and I have edited it and saved this edited version as a local postscript. But neither of this postscripts gives me good result. I have set my stepmotor to 1/2 step and with 400 steps the gear-mechanism turns 144 deg. So I have set 400 step per r...
