General Mach Discussion / Re: Help getting my machine running...

« on: November 19, 2011, 11:16:18 AM »

Your screen shot shows that your printer port is on 03BC not 03BM..... try both IO ranges in the ports and pins Both 03bc  if that doesnt work then try 03be

The clunk your getting is the stepper drives energizing.  All that means is that you are getting power to the motors from the drives.  It has nothing to do with the computer talking to the controller.

Hello everyone. Great forum you guys have here. I have been reading for a while up to today when I finished putting my machine together and got ready to get it running.

I downloaded Mach3 demo, added the XML file and ran the driver test. Then I followed some instructions and set up Mach3.

So far, no movement at all. First, I am running Mach3 on a laptop. Its an older IBM with a built in printer port. 1.7Ghz, 1GB ram with Windows XP.
My Controller is a TB-6560. Looks like some toshiba parts but made in China.

My printer port is 03BM so I changed that in Mach3. Now when I try jogging I hear a little "clunk" coming from the motor but no movement at all.
Also, the driver test completed all the way but said during the test that the pulse was too fast?

Any help would be greatly appreciated.

Thanks

I would also recomend getting some thrust bearings for the motors if you dont have any already.  If you put thrust bearings inbetween the motors can and the screw coupler, and the motor can and the dampners it will keep the shaft from being able to move inside the motor can.  Which could result in backlash issues.  I know I had major problems with the xylotex 269 motors with massive amounts of shaft play inside the motor can.

if you need them, I am sure I can dig out my old rattler dampeners....

Take a look at these, your problem is the drive i bet you.  Find a way to make a dampener for testing.  you will be surprised.

Here is a good thread on dampeners. Resonance is horrid in the xylotex.  The vibration is going into the motor and builds up.  If you lower your accel way down and jog the motor so that it ramps up to speed, you will see that as it reaches full speed, it will stall.  Any setting in mach will not solve it

another thing to keep in mind, you are limited to a 24v power supply, which means that if you have say, the 269 ox steppers,  you are running them at less then half of their rated power.

what are you using for motion control?
does the machine run smooth or does it have resonance?

I had this problem with my old xylotex drive  The solution was a dampener.

I think I figured it out.
RFH does not like radius commands.
I used the circular pocket wizard with X and Y as the center.  So the code had y0 in front of every line.  Then a radius off of that.
Explains why when you RFH after jogging each axis, the prep move wants to go to Y0  which does not put the tool back into the same position as when the machine stopped.

another test
mach 3 on my laptop...... bare install using the default xml  No plug ins of any kind.
vers .028

I still get the y0 on the prep move

just for argument sake, I upgraded mach to the .053
Still no change

im not worried about the PP machine, do you want the SS XML?
