Test the v3 duel and post findings here
@guadalupe @draubach can we get 3 more of the [EL-HR0187] TAZ Extruder Extension v4.0 that you made for Logan in MER? We will need these to test the Dual v3 on Workhorse. We will also need 3 [EL-HR0186] Dual V3 Adapter Harness. Cable drawings are in the repo, please let me know if you need help accessing them.
@west do you have 3 of the printed mounts?
I was trying to install the mount on our workhorse, and it looks like there is a part that is interfering with the mount. Pics attached.
Not sure if the one that I have is an old revision, or if others are seeing this too.
Was able to get a modified mount, so the tool head is able to rest well on the printer without any wobble. I was able to do a print with it, a PLA/PLA Moai head that came out rather well.
There is an extremely tight tolerance with the frame of the printer, but not something that I have run into an issue with, but it may cause some concern with customers on first install.
When I was first installing it, I wired it similarly to how the Taz 6 was wired, with the additional harness attaching to the E1 side, and the default harness to the E2 side, but on redgum, it is swapped around, so we will need to make that clear in the documentation that there is a difference there.
I'll do a few more tests through the day, and post what I find.
Doing the backlash calibration, it looks like the two hot ends are interfering with each other, causing the results to be either very skewed, or just cause the process to outright fail.
We were warned about this and so backlash compensation will not be available for the dual on this machine.
@marcio is it possible to modify the backlash routine to account for both nozzles (using one nozzle of one side and the other nozzle for the other perhaps) or removing the backlash compensation from the menu in dual v3 firmware?
