UGS and Jogging issues (step size)

[nholt]

Hey everyone,

I have two problems but they might be related. I'm currently assembling the M3 and I'm at the point where I test the jog of the motors. I downloaded the Universal G Code Sender program from here: winder.github.io/ugs_website/download/ (2.0 Platform (Beta)) and also the 64 bit version of Java 8+. I'm running on a Windows 10 (64 bit) laptop.

First problem occurs when I try to run ugsplatform64.exe, I get the error "Cannot find java 1.7 or higher". I've verified that I have Java installed correctly by typing  "java -version" into the terminal. The error still remains after restarting the computer and browsers.

I can work around this by running ugsplatform.exe, which is presumably the 32-bit version. In this case the program works and I can control all 3 axes through the program, but I noticed something was off and this is problem #2. The step size is larger than 1mm for all 3 axes (I crudely measured 6mm of travel for the Z-axis when Z+ is clicked). All settings in the Jog Control tab are the same as the manual (I believe it's the last photo in the manual). Is there an extra setting I forgot/missed or is this just due to using the ugsplatform.exe?

Has anyone else ran into these issues? Thanks in advance for any help.

I had the same issue where ugsplatform64.exe would not run on my Win10/64-bit laptop. Ugsplatform.exe works just fine however, so I don't worry about it.

Regarding the jog size, are you sure you don't have "inch" selected instead of "mm" in the job control window? Are the jog sizes off by the same amount in the other axes?

[nholt]

Yeah, I thought the same thing as well, but I did verify the system was in "mm" through the command G21 being sent (and it should be ~25mm movement if that were the case). Thanks for the ugsplatform.exe info, good to know.

After thinking about it now, I might have messed up the jumpers on the CNC shield (pg. 29 in the manual). This would certainly explain the weird step size and why it was the same for all axes. I think I placed the jumper across M0 and M1 (horizontally if you're looking at it the way the pictures in the manual show it, so M0 and M1 pins are connected), but after rereading it I think I need to place the jumpers vertically (like across both pins that are M# related). I will report back tomorrow if this solves the problem or not.

I can confirm they should be vertical and that this should solve your issue.

[nholt]

Yeah, the jumpers were the problem, everything is good to go!

Glad to hear it. Be sure to share your projects.

I got the Java issue when I started... you need to reboot the computer after installing.

I have rebooted the computer after installing Java and I still have the problem with ugsplatform64.exe listed above. Using the non-64bit version is a quick workaround and so far I've done a drawing test with a pen in the machine and have not found any issues.

That is exactly the situation I ran into with my Win10/64 laptop, but I have since switched to an old laptop running Ubuntu Linux so that it can stay out in the garage with the machine.
