So today my new PCB arrived, (they sent me a new one, regardless that the one I have was working properly) I put it on, and the same issue still. IT sounds impossible really, all the PCBs are fine, all of them operates the Y and the Z axis properly. But none of the PCBs operates the X-axis. the connector and the motor wiring is also correct, because every single motor runs on the Z and Y axis connectors.
Now the only explanation is that something wrong with the main board. Either the motor connector pins, or the PCB connector part because whatever combination I use, it just does not work. From the outside, I cannot see any short circuits, the board is not cracked, and installed to the frame correctly with the plastic spacers.
I was also thinking that there might be a problem with the motor stop switch, and it might turns the motor off straight away when I enter the commands to move, but I disconnected it, and checked all the wires, and it still doesn’t work.
I was experimenting with the PCB voltage as well, all of them set correctly 0.425V, I also tried to increase it til 0.55-0.6 on the X-axis but still nothing. The motor recieves the instructions, because it buzzes when I try to move it, and if I hit StopMotor button it swtiches off.
What could possibly go wrong on the MainBoard? or can I further check it somehow if there is something wrong with that?
When you connect everything as it should be your X motor is not working.
If you disconnect the connector from the X motor and plug it in the Y connector on the mainboard and the Y motor in X motor connector on the mainboard, both motors are working?
If this is the problem you are having it sounds impossible yes…
either a driver is broken but then no motor you plug into that should be working or a motor is broken and then it shouldn’t work on any driver…
Then their is indeed something wrong with the motherboard…
If you remove the driver of the bad channel you will see some words next to the pins can you check the solder points of the STEP and DIR pin. Also does the light light up for the broken channel if you give that channel a command?
If all the solder points look fine you can send the board (together with a description of the problem) to:
Velleman Repair Service
Legen Heirweg 33
9890 Gavere
Belgium
We will check the board and send you a new one ASAP free of charge.
I will check the soldering when I get home, but yes the LED lights up red and sometimes it freezes and keeps lighting while the motor is buzzing but do not move. When I hit Stop Motor then it switches off
