Haq XY

@dc42 No problem at all, I'm just thankfull for all the help

Can Haq XY-kinematics be used with RRF3/6HC mainboard?
I'm planning on changing from 3-axis (x,y,z) Corexy to Haq XY (x,u,y,z) but I need to be sure there is a working firmware for it. I use 6HC mainboard in my machine so I assume I cannot use binary posted several post above. -
Yes, RepRapFirmware supports any kinematics for which the movement of each axis is a linear combination of the movement of the motors.

Hi everyone,
Are you able to share how you set this up? I'm currently knew to RepRap Firmware, as I'm a long time user of Marlin but due to the fact Marlin doesn't support this type of configuration. I'm currently looking to move over to RepRap Firmware and purchase a Duet 3 6HC board.
I've actually already built this printer, photos attached. Its still got a little bit of work todo and due to the nature of Duet, Reprap and the open source community I intend to share this project among my other projects (Root CNC).
I would much appreciate any help on configuring this type of kinematics as it looks like I'll be taking a big leap into the world of duet and RepRap firmware and I hope it'll soften the blow.
appreciate the help!
Thanks in advance! Pete from Root CNC

@RootCNC Hi,
Sure I can share how to set it up.
But I'm having a hard time understanding how you route your belts to make it a Haq-XY kinematics? -
Ah sorry about that - Please see this photo.
I currently have two motors driving the Y axis - these shall be configured in a series configuration.
then two independent carriages driven from independent steppers.
Does that help?
Thanks
-
@RootCNC Aha I see!
I routed my 2 X belts on the same route but at different heights instead
And I used one stepper for the Y axis but with a rod connecting both sides of the Y axis.But the kinematics are exactly the same.
Btw, are you stepper mounted in the bottom with rods going to the top?
-
Yeah, to keep its low profile and symmetrical I went this way with the belts.
I plan in the future to try a heated chamber, so keeping the motors below the 6mm plate seemed a good idea.
I just purchased my Duet 3 and LCD, hopefully it'll turn up soon and then we can get this printer moving!
Was the setup difficult?

@dc42 I just reversed the Y motor and when I do G1 X10 F1000 S2 the Y axis moves in the right direction (+10).
But I've noticed a new thing when homing.
This is my homeall.g now:G91 ; relative positioning G1 Z5 F6000 S2 ; lift Z relative to current position G1 S1 Y550 U540 X-540 F2500 ; move quickly to Y axis endstops and stop there (first pass) G1 S1 Y550 F2500 ; Home Y seperate G1 S1 X-540 F2500 ; Home X seperate G1 S1 U540 F2500 ; Home U seperate G1 Y-5 X5 U-5 F2000 ; Go back 5mm on all axis G1 S1 Y550 F600 ; slowly home Y G1 S1 X-100 F600 ; Slowly home X G1 S1 U100 F600 ; Slowly home U G90 ; absolute positioning G1 X300 Y310 F2500 ; go to first bed probe point and home Z G30 ; home Z by probing the bed G91 ; relative positioning G1 S2 Z5 F100 ; lift Z relative to current position G90 ; absolute positioningBut when it comes to G1 X300 Y310 F2500 the X axis just smashes into it's endstop.
It seems like both U and X looses their position somehow, or that X and U switches...so X becomes U and U becomes X.If I manually home Y first and then try to home X the U axis moves.
If I manually home U and X first, their postion is X0 U550.
If I then home Y manually X position is X1100.3 and U is U-560.Does this make any sense at all?
I am still having this bug, even after updating from the latest beta to 3.2 stable.
When I home one axis, the other two lose their position. Although I think the correct axis are moving when they are homing. -
I had problem where when doing homing U and X axes lost position during all axis homing. Those axes moved against endstops and lost steps/belt skipped.
This was because homeall.g included wrong move type: 1 motor move -type move (H2-command)
I switched it to H0. I think that you are also suppose to use H-command instead of S-commands.check: https://duet3d.dozuki.com/Wiki/Gcode#Section_G0_G1_Move
My corrected homeall.g

@Visionary
Would you do me a favour and post your config file? I think with my setup there is more wrong than just the homing file.

That will have changed the direction of X axis movement too.Duet WiFi hardware designer and firmware engineer

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....

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)

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.
-
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?

@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.
