I really need help now …
I can not get the x-axis to move when I use
arrows in easel.
It stands just pecking at the same place.
I have checked all the cables as they appear on the mounting video
And as I see it, I have linked them properly
However, when I have turned off the power
and pushing the x-axis by hand as it goes well
in my opinion

Does the sound changes when trying to move the X axis while energized? you might need to trim the current pots. I used 1.6V as reference.
Hi, I'm still having a few issues with losing position on the X & Y axis occasionally (1000x1000 X-Carve). I'm tending to suspect that it's an electrical issue (I'm not a sparky, so after checking all the mechanical stuff, I guess I always 'blame' the electronics).
My question is this: Is there an easy way for me to measure and then set, the current (and or voltage) that I'm sending to the stepper motors? I understand the basic difference between current and voltage and have a good quality met…
I had an issue with both the X and Z when I tried to move them the first time.
First I checked that I didn’t have the V-Wheels too tight. But still had issues.
Then I realized I needed to check the motor drivers power. I had skipped over this part when building my X-Controller.
Once I set the trim pots for the NEMA 23s they worked well and I did my first carve last night.
@eried said, check y our trim pots on your motor drivers.
Thank´s for your answer
But… sinse I´m a nebee on this
will you please show me thru pictures where the trim pots are.
The potentiometers on the gShield are setting the Vref (Voltage Reference) level on the TI stepper motor driver chips. This determines the current limit for the driver.
You can measure this voltage at one of the potentiometer pins (see photo) and adjust it to obtain a given current limit. Use great care as the potentiometer pins are very close to other components and it is easy to short the pins together with your meter probe. Really bad things happen.
The gShield (version 5) uses a 0.1 ohm …
It will be different if you have an X-Controller vs the standard electronics.
If you happen to have an X-Controller, I will be happy to make a video tonight when I get home about how to do it.
Please explain X-Controller vs the standard electronics
As I said before, I´m a newbee with this
