Haq XY

RootCNC

Hey everyone,

last night I got my HAQ XY or markforged IDEX printer moving and homing correctly last night.

you can see it moving here: https://fb.watch/38agipCwQx/

Here is my config, once you get your head around the matrix manipulation it was easy to ensure it was moving in the correct direction.

The magic happens on M669 command....

Homing wise:
here is an example of my homing script (the standard IDEX setup guild is very good)

; homex.g
; called to home the X axis
M400
M913 X50 U50 Y50 ; drop motor current to 70%
M400 
G91; relative positioning
;G1 H2 Z10 F12000 ; lift Z relative to current position
G1 H1 X-320.5 F10000 ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X5 F12000 ; go back a few mm
G1 H1 X-320.5 F7000 ; move slowly to X axis endstop once more (second pass)
;G1 H2 Z-10 F6000 ; lower Z again
G90 ; absolute positioning
M400
M913 X100 U100 Y100 ; return current to 100%
M400

Please note I'm doing sensorless homing

@MaxGyver said in Haq XY:

@dc42 I just reversed the Y motor and when I do G1 X10 F1000 S2 the Y axis moves in the right direction (+10).

That will have changed the direction of X axis movement too.

I'm sorry, that would have been correct for CoreXY kinematics, not MarkForged kinematics. HaqXY is dual MarkForged.

Note that I'am too trying to get my printer working correctly. I have some problems for example with tool offsets. Please make sure that any parameters you take from it are correct for your machine.

I have tested multiple configurations, but the issue is persistent.

Every time I home Y-Axis, the distance the axis has to travel to hit the end stop minus the amount it is allowed to travel is added to X and U.

Example:

I set the Y-Axis at a distance of 100mm from the endstop and restart the printer to set everything to zero.
I run homey.g

G91 			; relative positioning
G1 H1 Y-330 F2500	; coarse home Y
G90 			; absolute positioning

Y is now 0, X is -230 and U is at 230

(-230mm = 100mm distance to Endstop -330mm maximum homing distance as specified homey.g)

I don't know what I am missing here...

In my HaqXY I have X-, Y- and Z-axes endstops at low end of the axes, but in your config.g you have Z- and X-axis endstops at high end. Is this on purpose? Only axis that I home to high end is U-axis.

@MaxGyver said in Haq XY:

Every time I home Y-Axis, the distance the axis has to travel to hit the end stop minus the amount it is allowed to travel is added to X and U.

That's either a firmware bug that nobody else has reported, or an incorrect matrix, or an incorrect homing file.

After homing both X and Y (or sending G92 X0 Y0 to pretend they are homed), do normal G1 Xxx and G1 Yyy moves with no H parameter work correctly?

MaxGyver

@Visionary Yes, this is correct. I have my XUY zero at the rear right-hand side of my printer with the first extruder on the left (X-Axis) and the second on the right (U-Axis).

@dc42 Yes, these moves are executed correctly. I am using this printer for quite a while now. Most of the time this issue is not a problem since I rehome all axes before starting prints or executing macros. But If I don't rehome all axis in the correct order it leads to crashes.

Thans, I'll log this as a bug to be fixed in RRF 3.3.

Hi @MaxGyver, I have reproduced this and tracked down two issues that are causing it:

The first issue (the main one) is that when the homing move stops, the firmware needs to retrieve the number of steps taken by the X, Y and U motors. This data is not currently available for the X and U motors because they are CAN-connected and the move has been terminated early.
The second issue is that in config.g the M584 command should precede the M669 command, so that the U axis exists when you use M669 and in consequence it builds and inverts a 4x4 matrix instead of a 3x3 matrix.

I will work on a solution to the first issue.

I am glad to hear that! Thank you very much for your feedback.
