Need help Homing sequence in H-bot( CoreXY) system

Thanks.
I changed the position of corexy to be in the 3rd (as far as I remeber) positionin the servo thread queue, and I increased the FERROR parameters for Joint 0 and 1 from 1 to 2.
Now the machine is working great, as far as I can tell. It can reach 60000mm/mn in fast jog. This is great.
There is still a lot to do: wiring, tuning, etc...

Anyway, thanks a lot for your help.

Attached is a picture of the machine under construction (sorry for the mess!). The overall size is 1m x 1.5m. It' based on the Workbee design and I have added a second CoreXY type gantry for 3d printing (in the front). This good think about it is that the motors are not moving with the gantry, allowing less moving weight and consequently better accelerations. The original gantry (in the back) will be used for routing wood and machining wood, plastic or aluminium parts.

Best regards,
Bernard

Hi,

I'll make it simple: I plan to use one OR the other: I'll "park" all the way on Y the unused gantry.
And I'll load a different configuration files :
- one for 3D printing,
- and one other for CNC machining,
- and maybe one day, a different one for a laser cutter/engraver

In order to save some IO, I had to share some stepper outputs between the 2 gantries (eg X of CNC=Joint0 of coreXY, Y of CNC=Joint1 of corexy...) I'll use the Enable signal of the stepper drivers to choose between one stepper ot the other.

What do you mean by "You could configure one system to be a toolchanger for the other." Could you develop a bit ?

There is also a new post with a corexy component just posted on this thread here;

I hope the devs pick up one of these solutions and integrate into the core code. The other one is on github if it helps.
