Title: Mach 3 Feed Rate very slow
Post by: Kalyptos on April 20, 2014, 08:56:04 PM

I have a Tonsen 3040c h80. I have installed the trial version of Mach 3. Regardless if the speed setting ( for examp F4000) it shows approximately 8-9 units/min. When I increase feed override to 4000 it still only runs at 8-9. Anyone else have this problem.

What is you max vel set at in motor tuning ?
If you G0 X100 will it rapid at that above rate ? (from X0 of course)
Did you try G1 X100 F4000 ? (from X0 of course)

Max vel is 4000, will not feed at that rate, feed rate consistently shows 8-9.

Attach your xml, might see something there.
Can you JOG at the full rate ?

I believe that is a pirated version of the software.
Do a fresh download of the DEMO version from the website.
Then try it.

Yes, I think it is too, It was labelled as the 'Demo' and came with the CNC. I noticed it had a bogus 'user', have uninstalled it and downloaded the new version, and this is the one I am having trouble with. Perhaps it is holding a setting or something from the old install.

I have edited the 'User' out of the xml, perhaps that will work.

OK, here is the new XML, did a Registry keyword wipe, and a hard drive dirty word search and delete. This should be a clean install, Jog rate is 1.5-2 Units/Min, and Feed Rate is still 6-8.

Looking like I will go to a USB controller if there is no joy - It will be twice the price of the Mach3 license but if something doesn't work...

Thanks for any assistance.

So - just noticed this section -

<Vel0>6.667</Vel0>
      <Acc0>200.</Acc0>
      <Steps0>320.</Steps0>
      <Vel1>6.667</Vel1>
      <Acc1>200.</Acc1>
      <Steps1>320.</Steps1>
      <Vel2>6.667</Vel2>
      <Acc2>100.</Acc2>
      <Steps2>320.</Steps2>

Is the Vel* the feedrate?

I am pretty sure it shows as 4000 in the GUI, but 6.667 here?

there are other programs that will make M3 act that way .. firefox is one . if I have it  loaded with M3 the feed is very very slow.
make sure nothing else is running in the background. I have heard of other prgms that don't play well with M3 either. quicktime hides in the background and causes issues too.
