Hi Mariss, Just as you say, I started by turning towards the drive. After all brand new encoders should simply just work.... I've got the differential version...
For what it's worth, I put an E3 encoder on one axis to try it out. It worked fine and the other two axis encoders are due at my door today. I did not use...
im using g203 gecko driving my stepper motors along with cnc4pc bob c23.. and smooth stepper.. had my cnc unit allmost set up... when today the z axis behaves...
I had similar experiences before, it could be a bad parallel port problem, try switch the cpu. hope it helps. fortino To: geckodrive@yahoogroups.com From:...
im using a smooth stepper its a usb connection when i switch x-z cables to the motor....the problem switched to that motor ie z motor ok x motor then has...
thanks to everyone that help me... i got it resolved, it was cable problem in a terminal block, the 18 awg wires got compress at terminal block cause...
hi all, does anyone now of an electronic module that can give me analog output 0-10v ,proportional to spindle loading current? can i expect a 3 phase motor to...
... No, the current of an induction motor is not at all proportional to load. The current remains nearly the same, but the phase angle between the current and...
Hi, Rather than doing the research myself :), does anyone know if a stepper will hold its position at rated torque, or will there be some error? If so, is it ...
... Yes, standing still, at rated holding torque, the error is almost exactly two full steps. If the error ever exceeds 2 full steps, the motor will jump to...
Peter, Steppers can be dumb ass simple to run, but you will be far better off to do the basic research. Simple solutions and they turn, with a bit of study and...
... Hi, not exactly, I think the correct formula is torque = sin (pi/2 * dp) * rated torque with dp = position deviation in full steps. So the maximum torque...
many thanks Jon and John for the help. the links and info helped me a lot. I am suspecting the loading controls will be useful for cnc marble grinding. i...
... You really should take another look at EMC2. I'll send you another disc with the latest if you need it :) Once you get the load signal into the PC (there...
thanks steve, the offer is most welcome. my only rant with emc2 is i could not become an active developper of emc2,after a few months of reading around,and...
... Yes, there's a lot of code and a lot of documentation. Even in the areas that have sufficient documentation, it can be hard to find what you want (due to...
i will definitely get there,(using emc2 for all my systems),but my funding is in phases. I have to get things running and financially productive,even if its a...
... Hmmm. How hard did you look for python code? :) Here's what you need to do to be able to control EMC2 from python: import emc import hal Done. :) An...
Hello All, First off, thanks for entertaining my question. The machine I'm building is going to use a Keiling KL23H251-24-8B stepper. This is a 3.5A stepper....
I currently have: * g540 * (3) Keling KL23H286-20-8B spec: http://www.kelinginc.net/KL23H286-20-08B.pdf * Keling KL-600-48 power supply Do I want to wire these...
In the Rev-4 Users Manual of January 14, 2009, Number 6 says to jumper pins 10 and 12 on the 12 position block to enable the drive and exit Fault. I didn't do...
I've just set up a Taig mill and a Gecko 540. This is the error I get in Notepad from Mach3 after going through the setup routine and trying to jog the x...
Just to muddy the water a little bit; it also depends on whether the motor is run open-loop or closed-loop. In closed-loop the position accuracy is +/-0.5...
The G540 has four of the G251 drives inside plugged into a nice opto-isolated motherboard (break out board). It is a great way to go. The folks I have sold...
