Mach4 General Discussion / Machine Freezes Followed by Unwanted Offset

« on: November 02, 2020, 08:05:35 AM »

Hello Mach4 Forum

We are currently running 3 AVID CNC Pro 2448 Machines that all show a similar issue that occurs on an intermit basis.

We will be running a known and tested file but the machine will suddenly pause (on its own) mid cycle for 3-4 seconds followed by an offset usually X and Y. Understandably this will ruin the work and is quite disruptive. The offset is not 'programmed' rather the machine has lost steps and lost position. This lost position seems to be due to some kind of digital interruption - the machine is certainly not mechanically overloaded at the time that it looses steps.

Admittedly the PCs that we are using seem to be underpowered in terms of graphics card (Mach4 states 256 to 512 of dedicated graphics RAM) and I don't think our PC actually has a dedicated graphics card. (PC spec here: https://www.amazon.co.uk/gp/product/B07MPPW7JY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1).

My question is does this seem to be a symptom of underpowered graphics or is this likely to be coming from somewhere else?

Any pointers would be very helpful.
Thanks.

G-Code, CAD, and CAM discussions / Re: Feed Rate mm/sec to mm/min

UPDATE

I think I was not completely clear earlier. We have a large library of g-code files (around 300) and want to run these directly on our new machine Mach3 CNCRP Pro. The code seems to work fine (with a few settings changed) except for the feed rate which is at mm/sec in the file and mm/min in Mach3.

Making changes to the post processor or g-code is not really an option as it will mean having to manually alter over 300 files - it may come to this but I would like to avoid it.

So my question is can I change the feed rate units at the Mach3 end of things? - not the post processor or gcode end.

Many thanks

G-Code, CAD, and CAM discussions / Feed Rate mm/sec to mm/min

Hello

I have a feed rate issue from running a Multicam Post Processed file on Mach3 for CNCRP.

I think I have fixed most of the other problems but cannot find a way of changing the feed rate units from mm/sec to mm/min without manually changing the g-code itself.

Is there a setting in Mach3 I can change for this?

Many thanks
