General Mach Discussion / Re: Z Axis Stops Working / Fails To Move
« on: August 13, 2012, 09:18:45 AM »
Thanks Overloaded. Checked through all the wiring and connections and all looks good so don't think its the root cause of the issue I'm seeing here. I ran the program again over the weekend and the same thing happened (at a different point in the program) with the G0 Z3.0 return to safe Z command. It's a large 2.5D file with 450,000 lines so I can't really sit there and watch it continuously but I did catch what I think was the motor stalling when moving the Z and hence had to reset the Z height. By the time this had happend I was already through 20,000 lines of code so its definitly not a regular occurance and struggle to understand how it could be a motor tuning issue.

Any ideas?  ::)

General Mach Discussion / Z Axis Stops Working / Fails To Move
« on: August 06, 2012, 07:00:16 AM »
Hi All,

I'm new to CNC'ing and Mach3 but over the last couple of months have slowly been working through the issues with my Taig2000 micro mill setup with a Microproto controller which I recently purchased second hand.

After many, many hours of setting up and debugging the setup I thought I had it sussed but I now have one final issue to resolve.

I was machining a part over the weekend and all was looking good until disaster happened. At end of a profile run the Z axis didn't physically move back its safe height even though the DRO on Mach3 showed that it did. The motor itself didn't make any noise so it wasn't stalled as I had when configuring the machine initially (I know that noise well), it just didn't move. The consequence of this was a nice machined groove across the surface of my part and then the Z axis tried to plunge the bit back through the work piece due to it being out of position relative to the DRO.

I think I may have caught a situation a little like this before where when jogging around the Z axis fails to respond. If I then move either the X or Y axis and go back to the Z axis it then moves normally (I have never looked to see if the DRO is still moving in this situation). I am using the Joypad plugin with a Logitec Joypad to jog and I had wondered if this could cause have caused this issue but not sure if would have any affect when running a program.

I have Mach3 R3.043.022 installed and I'm now running on a 3GHz P4 dedicated PC with a PCI parallel card and all the suggested windows XP optimizations in place after a lot of trial and error to begin with.

Anyone have any suggestions?  ???


Well I removed both versions of Mach 3 and re-installed the latest one and all seems to work fine!

Thought I'd better close the thread out!

Cheers for the help.

I'm using an xp laptop which I've just rebuilt so apart from Mach 3 the only other thing it's running is FreeMill (which isn't a lot of use as you can't seem to set max cutting step depth). I also have the joypad plugin installed and running.

I do have 2 versions of Mach 3 installed as the mill came with a copy of an older version but only running with the latest one I just downloaded. Could this cause an issue? Hummhhh.

Not with the computure at the moment but will post the XML as soon as I get a chance tomorrow.

Thanks for the quick response guys!

Hi, I've just bought a second hand taig micro mill 2000 with a microproto stepper controller and I'm currently trying to set up Mach3 to run it. I downloaded the XML available from this site specifically for my setup and after a lot of messing around with parallel port configurations I'm now almost there.

The final issue I appear to have is that the pin numbers change during operation. When I first fire up Mach3 every thing works fine and I can jog the axis or run a program ok. Shortly after startup, anything from 30 seconds to 3 minutes, one or more of the axis will suddenly stop functioning. This primerrily effects the x axis but has also occurred occasionally on both y and z as well.

After a lot of head scratching and cups of tea I have tracked the issue down to Pin numbers being changed randomly whilst using the software. When I first start Mach3 I check the pin assignments are as set in the XML and everything works fine. Once the issue occurs if I go back into the pin and port settings I can see that the step pin number assigned to the effected axis has been changed to something different to that originally configured.  If I then change the pin back to what it should be it fires back into life.... Until the same thing happens again a few minutes later.

I would like to get this sorted before shelling out for a license so would appreciate anyone's help.

PS. I have seen someone else had a similar issue but there was no response on the forum.
