Hello all.
I finished my taz6 clone but i have a problem with z homming.
When I execute a home all the nozzle goes down but it is in front of the end button of z approximately 2cm.
I have checked all the limit switches with M119 and they are all correct (all in open) and they change to triggered when there is any pressed.
I update firmware to 1.1.9.34 lulzbot Aerostruder with cura 3.6.20 after cleaning all cache before install Cura.
If someone who has happened can help me, I appreciate it.
Is the Z end button in exactly the same location on the clone as it is on a “real” TAZ 6? Are the X and Y endstops in exactly the same locations as a “real” TAZ 6?
After a G28 XY my Aerostruder is sitting at Recv: X:-19.00 Y:258.00 Z:5.00 E:0.00. The nozzle is centered on the Z end button. This is with 1.1.9.34 firmware.
Coincidentally, the Single Extruder v2.1 is at the exact same coordinates and is also centered on the button.
If the X and Y endstops and the Z end button are not in the same relative positions (and can’t be moved), then you may need to customize your firmware.
is exact in measures clone to Taz 6 only is china rambo clone
X:-19.00 Y:258.00 Z:5.00 E:0.00 Count X:-1910 Y:25929 Z:8000
but the nozzle around 2 cm to the front
Not sure what to say. I’d check G0 X0 Y0, G0 X0 Y280, G0 X280 Y280, and G0 X280 Y0 and verify that the nozzle reaches all four corners of the bed.
You probably can’t do G29 V4 until you can get a valid Z position. What do you get from M115 and M503?

all in bad position …
Maybe my firmware is bad?
Can you send me your firmware and i upload manually?
Thx
I got mine from http://devel.lulzbot.com/software/Marlin/.
I think i found the problem,
I suspect that when I bought the GT2 pulleys they sent me 20 teeth and not 16 teeth.
Can I configure the steps for these pulleys or do I need to buy one with 16 teeth?
You probably can configure the steps for the 20 tooth pulley. It should be similar to the process used to calculate a new esteps, i.e. tell the system to move 100mm, measure how far it actually moved, and use that ratio to adjust the current steps value.
If it was me, I’d order the 16 tooth pulleys and then see if I can adjust for the 20 tooth while I waited for the 16s to arrive.
Yes i order new ones of 16 tooth.
I configure the e-steps to 80 and all working good.
Next week i update with results,
Best regards
I installed 16 tooth pulleys and all very good with a few models but now a new problem appear.
The Y axis begin to lose steps and i found the drivers in rambo are very very hot .
When i power on the printer is good but in few seconds when the motors are running the drivers very hot…
Is a problem of broken rambo board?
It could be either the drivers on the board or too much current being drawn by the Y stepper.
Do the drivers have heat sinks? Can you swap the Y axis stepper motor with the easiest one (i.e. don’t care if its X or Z or a spare)? This should tell you if its the drivers or the stepper motor.
