Hi we are in need of an engineer in the west midlands we are based in Digbeth. Our machine is cutting at 2.5 x its size in both y and x axis. If any one could suggest one that would be great thank you

This might be just a scale problem ie metric, imperial is the software or CAM G20, G21Quote:

I am starting to think that maybe there is a dodgey connection some where as i am unsure as to why this is happening. We have had the pendant apart to check everything is in tact in there and all is fine.
Thank you for your advice!
G17 is the XY plane G20 is for imperial and G21 is for metric.Quote:

In the MDI type G1 X0 F200 then G1 X10 F200 Then check to see if X moved 10mm
This won't be a dodgy connection or bad wire issue. It will 99.99% be a parameter change in the pendant or G-code.Quote:

To be honest It's typical of the kind of issues these DSP style pendants can suffer from and often they just blow their minds (parameters) and never run again. In this case, it's better to just rip them out and install PC based motion controller.
Often the machine runs better and the PC control software gives far more control and better operator experience.
If you can post the G-code file I will take a look for you and check the code. Just Zip it up and post the file.
Hi yes it is running fine just on a much larger scale .We have ordered a new pendant and wire so they are on the way but we have been told before to change to the pc version as it is much easier to use. We are bearing this in mind but think we will wait until the new pendant arrives to test that first. i have inserted the G code below as wellQuote:

I can't see anything wrong with the file apart from not having a G21 at the topQuote:

As a workaround could you reduce the DXF file in Vcarve with scale .
It is under "transform objects set size". and reduce it with the %

Do you know if i would need anything new to connect my pc with Mach 3 on it to my rich auto circuit board. I'm thinking a new circuit board but unsure as to which one ?
Many Thanks Bria
I use ' Discriminator ' for working on Gcode can scale edit very easily
