2nd independent Z-Axis labeled V Homing failed
-
@o_lampe OK, I do not have a M669, but looks like I need it. Reading up on, trying to understand it. I've actually upgraded to 3.3.RC2 and will test G38.2 and see if that works
-
@o_lampe Hi, so for a cartesian printer would this be correct:
M669 K0 X1:0:0 Y0:1:0 Z0:0:1 U1:0:0 V0:0:1 -
@jsinicro What is the target position in G38.2 V? P0
-
@jsinicro OK, I tested it target position basically how much to lower the axis. However the V axis moves down the correct probe deploys and once it hits the bed it retracts and stops moving, but I still get Homing failed.
-
@jsinicro if I also send the command manually G28 V the axis does move down the probe triggers axis stops but I the error G28 V probe was not triggered during probing move the I get Error Homing failed. But it triggered and stopped moving. What could be going on?
-
@jsinicro I remember reading something about the probe needing to be on the same board as the motors but that was fixed on 3.3RC2 I thought?
-
@jsinicro I don't think that's it because the main Z axis has the motors on the main board and the Bltouch is on the expansion board.

@o_lampe Hi, so for a cartesian printer would this be correct:
M669 K0 X1:0:0 Y0:1:0 Z0:0:1 U1:0:0 V0:0:1I'm confused about your printer config. It seems you have 4 x-motors and 4 z-motors. Then this kinematic model can't be right...
You also have to define tool objects to tell the firmware which X- or Z-motor combo is 'on duty'.
What's your plan anyway? Do you want to print with both tools in copy mode or should they work on the same part (simultaneously?)You should start with the basics and see if you can move each axis the way it is supposed to move. Use G92 to set the coords manually, then use the jog control to move.
Then we talk about Z-probes and homing. I hope I get some help here, since I believe only one BLTouch per printer is allowed, but several probes of other types are possible.

@o_lampe There are 2 motors on each z axis and 1 motor on each Y axis I actually got this to work as fine as homing and moving correctly. I found a way to home both Z axis by adding the commands to the homez.g. What it does is first map the first Z axis with the first 2 motors then it remaps the 2nd Z axis with the other 2 motors and after it's done it combines all the motors into one Z axis motor.
It would be my goal to have both tools to extrude simultaneously on the same part so that basically it would cut the print time in 1/2. The chassis that I need to build for autonomous vehicle is divided into 3 parts and 2 of these parts took about 4 days to print -this was on a printer I bought but was very disappointed with it. I then decided to build my own.

Good to hear you've sorted it out.
To print simultaneously, you'll have to be patient. The firmware isn't yet able to do it.
Can't you print a mold and do fibre/resin casting?
