Re: Troubleshooting Comet

Got it figured, wasn't the config files at all. When I ran EMC2 from the applications it was running the old program, one of the guys told me to go into the home folder, rename EMC2 folder to EMC2_OLD then take the LinuxCNC folder and rename it EMC2 so the application pointed to the "new" ...

Re: Troubleshooting Comet

Well everything works, but the configuration is somehow off. In the instructions for conversion it says to install a different file ( proboitx Unity Conversion install.zip ) so that is what I used. Upon start up I find the axis travel at half speed and when it supposed to go 10" it only goes 5&...

Re: Troubleshooting Comet

Just printing off the conversion for the motors now, fingers crossed all is good after installing the new unit controller so I can get back to working on prototypes.

Re: Troubleshooting Comet

Was just posting this and I received a response from Probotix, they gave me this link for the conversion: http://www.probotix.com/wiki/index.php/Unipolar_to_BiPolar_Conversion It seems odd to leave the Z Axis, I would have assumed X, Y1, Y2, Z and your saying its X,Y1,Y2,A ? What do you do with the ...

Re: Troubleshooting Comet

Yes, I have an inquiry on that unit, I wanted to know if it's a "plug and play" replacement for my old unit. The old Controller has four axis ( XYZA ) where as the new one has five Axis so I was curious if I need to reconfigure things in software or rewire things with respect to connectors...

Re: Troubleshooting Comet

Thanks for that information, based on the data sheet I think all of the probostep drivers are likely damaged, I'm fairly certain that all the logic circuits were hit with a voltage spike the logic circuits could not handle ( example 40V instead of 5V ) The SLA requires 3.3 min to 5.5V max Vdd ( logi...

Re: Troubleshooting Comet

Long story short, I do not know what to do next, I wouldn't think that it's normal for the Probostep UX Rev1 motor drivers to load down the breakout board like this, given they each have their own fused 40V supply I would have thought it would have been just simple logic circuits, which should not l...

Re: Troubleshooting Comet

Very interesting, I removed the power to the breakout board and the damaged regulator to troubleshoot what is causing the short on the 5V supply. I measured 2.6 ohms between the +5V and GND which would indicated a required current of 1.9A at 5V The regulator is rated for 1.5A min ( 2.2A typical ) wh...

Re: Troubleshooting Comet

WOW That was not fun, definitely something on the PCB causing a short, replaced the LM317 regulator and got about 1V ( instead of 5V ) before it popped about 15 seconds into power up. And yes that literally what happened, it popped like popcorn ( allways wear safety glasses when testing unknown issu...

Re: Troubleshooting Comet

Alternatively for about $7 they could have had a DC/DC buck style converter to drop 40V to 12V then regulated that down to 5V, would have taken quite a bit of stress off the LM317 having to dissipate 35V of the 40V supply voltage at what ever current level.
