3dtouch probe failure?
Posted: Sat Aug 04, 2018 4:21 am
Hi all. I have just purchased a 3dtouch bed levelling probe, but Im hitting a wall.
I have an arduino mega 2560 ith a ramps 1.4 board, useing repetier 1.0.2 firmware.
This probe is suposed to work with this board and formware.
I installed it: first problem, I dont know why but the servo pins were not delivering 5V. So I conected + and gnd to the 5V from aux pins and the servo signal to the servo signal pin. the the 2 pin conector is conected to the Z min endstop pin.
firmware was confired folloing some instructions I gathered around internet, it should work at least as a min Z endstop. But it is not.
The probe starts and goes up and down 2 times, so that is suposed to be ok.
With gcode commands I can move up and down the probe.
I can trigger the autotest mode, it is supose to keep going until I stop it, but instead, it goes up and down between 7/15 times at best, and then it starts blinking. I reset the alarm, try again, and the same: self test runs 6/15 times before an alarm is trigered.
I have noticed that if the probe is not perfectly vertical, the alarm gets trigered more easily. So, the probe needs to be percetly vertical or may be the problem is that the pin probe is too loose?
If I cant get a sustained selftest mode, then I have t connclude that is faulty?
If I try to make a Z home it does weird things: it goes down, when the probe is trigered then it goes up, then it moves like trying to get to 0,0,0, and I have to stop it before that , if not the noozle would crash with a bed screw.
I dont know if this behaviours is because of a wrong firmware cofiguration or because the probe is faulty.
Please help,
Thanks in advance
