Tronxy X5S questions

TLeTourneau · 18 Oct 2018, 20:13

Hello,

Would anyone with a Tronxy X5S be willing to share their settings?

I'm having an issue with the x and y movement on my X5S after changing to a Duet 2 Ethernet. When I do either a X or Y move I get diagonal drift and I am trying to fix it. I am running the motors at 950mA with a 30% idle current percentage. I am wondering what other people have these settings at, I don't want to damage the motors. I've also replaced the stock bearings with toothed and smooth bearings with integrated belt guides. The bearings all move when turned by hand. I've read the article at https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter and am not understanding the process but I will keep trying.

Any advice is appreciated.

Thanks,

Tom

Can you post your config file as it is now?
And probably your homing files as well.

Thanks for the reply, I appreciate it! The motors are set for 1200 right now and it didn't seem to make a difference from 950.

What firmware version are you using?

Have you gone through the movement section of that link? Specifically the part where you move each motor independently to verify the motors are turning in the right direction?

TLeTourneau · 19 Oct 2018, 02:26

Thanks for asking about the independant X and Y tests. I just ran them and it look like the X motor is fine but the Y motor is having an issue. I will get a video, put it on YouTube, and link it here. Here are my firmware diagnostics.

Here is a video of running the X/Y tests: https://www.youtube.com/watch?v=ej4KsuKsWrg

Phaedrux · 19 Oct 2018, 04:23

Can you try this part? Or was this the part you tested in the video?

Commissioning
During commissioning, you can test the X and Y motors independently by using the S2 modifier on the G1 command, like this:

G91 ; relative mode
G1 S2 X10 ; move the X motor forward 10mm
G1 S2 X-10 ; move the X motor back 10mm
G1 S2 Y10 ; move the Y motor forward 10mm
G1 S2 Y-10 ; move the Y motor back 10mm
G90 ; back to absolute mode

Try it with the belts connected. And if it still stalls when moving the y motor. Try with the belts disconnected. If the motor turns the correct direction (watch when it turns and correlate it to how it would move the belts and the gantry) then we know you're configured correctly and can look closer for a mechanical issue.

You mention some binding in your video. With the belts disconnected can you move the print head smoothly in all directions?

Becareful when moving the print head with the belts connected to the motors. If you move too quickly you can generate enough current with the motors to damage the duet drivers. The speed you were moving should be fine but I wouldn't want to go any faster.

TLeTourneau · 19 Oct 2018, 05:49

Hello, that is what I was doing in the video. I created macros to do it quickly. I will try it without the belts after work tomorrow and update the thread. It doesn't seem any more or less difficult to move the gantry than before upgrading it. Thanks for the pointer about engaging the motors, I will be careful.

TLeTourneau · 19 Oct 2018, 17:53

TLeTourneau · 21 Oct 2018, 02:10

Y is working now, the cable had two bad crimps. I didn't check it first because I had a retired MM2 Senior Chief redo the cables for me (my brother). X and Y are now working correctly!

I want to thank everyone for the assistance, I truly appreciate it!

Phaedrux · 21 Oct 2018, 02:17

Glad you got it sorted.

Have fun with the rest of commissioning.
