General Mach Discussion / Re: 4th A axis irradical behaviour
« on: January 23, 2018, 03:50:43 AM »
Hi.

Yes. It might be the apparently pirated software thats causing this or perhaps my E-Cut 4 axis boards plugin isnt perfect. Im about to get a new license for Mach3 but waiting for funds and trying to understand if I also need to get a new board and if so what board is suitable. Would prefer USB or IP/network card with at least 4 axis.

I also tried to obtain a new version of the plugin to run the E-Cut board from Mach3 it but that has proven to be a hard nut to crack. The seller sent me an install of Mach3 .066 instead and refused to understand that it was their own plugin made for their own E-Cut board that was asked for.
Anyways.
I tried to figure out what caused the A axis problems and did narrow it down to some sort of soft limit
of the range. If I turned of A axis degrees in General Settings it had a range from  -2701.0142 to +2541.8655. Once the axis passed any of the liits it wrapped around to the other. So passing +2541.8655 would emediatly change it to -2701.0142 and then keep rotating in the same direction but with the new readout value.
I solved that temporarily by rewriting my G-Code a axis drilling software to use this new range instead of wrapping around 360 degrees. Works well with no glitches but the axis needs to rotate back to zero after each op. Not really a problem. Just a bit annoying :)

Ill be back once I have a new license but if anyone has any suggestions of a nice 4 axis board to replace y E-Cut board Im eager to listen. USB or IP.



Third attempt stalled A axis at first attempt to rotate 60 degrees. It got to something like 39.2343 degrees and then halted. Readouts in mach3 showed that halted position and it did not change but Mach3 kept following the code, drilling "new" holes but stuck in the same degrees.
Now that is really weird. I do not see how Mach3 can 'keep following the code and drilling holes' while the A axis DRO sits still. That just does not make sense.
However, a pirated license would explain almost everything. Only advice you will get here is to buy a real license from Artsoft.

Cheers
Roger

The "A" axis is tuned too fast for the selected kernel speed.
And ..... you are using pirated software.
You must correct that first.

Oh. Its NOT pirated!. I bought this from someone on ebay. Its not piracy to buy a license is it?
I will try to tune down the A Axis to see if that helps.

Tested freshly installed .062 and this time the problems start emediatly on first run.
Only A axis is affected.

I will try to generate a code using the wizard instead. See if its still the same..

Thank you. Attached the xml.
Just reinstalled completely fresh copy of .062 to test again.

Tweaki    I am getting ready to load a new laptop is .062 the solid locked down version...
thank you
archie

P.S. not meaning to hijack the thread

Hi Jeep534,

Popular opinion amongst our members here says that version .062 is the only one to use.

Tweakie.

Hi.

No skipping. Not at all. No errors like that that I can see.

No luck with .062 :(

It might have something to do with offsets some how.

Latest testrun was like this. Without the "Rot 360 rollover" or the "And Short Rot on G0" ticked in.

Started Mach3 0.62 with all new profile with new settings.
Made 2 succesful runs of code.  
Third attempt stalled A axis at first attempt to rotate 60 degrees. It got to something like 39.2343 degrees and then halted. Readouts in mach3 showed that halted position and it did not change but Mach3 kept following the code, drilling "new" holes but stuck in the same degrees.

It even read this "N200 G91 A60 F1500 (**Go Next Incremental Angle**)" and kept going after that even though the A axis didnt move.

I stopped the program and rewinded it. Then manualy jogged the A axis back to 0 and tried again with the same result.

It starts to move from A0 towards A60 but this time after A39.2343 it jumped directly to something like A-5236.3425.
I can jog back and forth and the jump keeps happening very accuratly.

Stumped!
Any suggestions?

Thank you!
Will try this now.

General Mach Discussion / 4th A axis irradical behaviour

Hi everyone.
I have used my 4-axis machine to create gears with great success but this past week it has started to act weird.

I have the A axis set to rotational angular and limit to 360 and shortcut G0 is active.
I use:
E-Cut 4axis board
Mach3 043.066
Win10 Pro x64


Heres a scenario example:

I load my code to drill 6 holes on a round part with 60 degrees between holes and finish one or two parts. Everything works as expected.
Then, instead of moving from A0 (or were ever the problem starts) to A60 it goes part of the way then suddenly skips to say A165.5347
The axis stops rotating were the big jump starts. The drilling commences.

I hit e stop and then I can jog back to the angle were it jumped from. Say it was 8.3562.

Now i can jog back and forth in one single small step from 8.3562 directly to A165.5347 but the head only rotates that single step.

Anyone familiar with this?
