I just received my new M175 V2 toolhead and the adapter for the TAZ 5/6. I installed it and I’m trying to install a new printer in Cura LE 4.13.17. The M175V2 option is available for Taz 6 but not for Taz 5. Please advise. Is there a plugin or something I need to install? I wouldn’t have bought the M175 V2 if I wasn’t convinced it was supported in the lulzbot store. If there is some gcode I need to edit, or even compile custom firmware, that’s fine. I haven’t experimented at that low of a level before on this hardware or with Cura LE, but if somebody could point me in the right direction I’d really like to get it working.
Just confirmed in 4.13.17:
It’s not labeled as the v2, but the only real difference in the two are nozzle offsets, which are relevant to the Taz6 which uses the nozzle for bed leveling. Not so much with the Taz5’s manual leveling.
Thank you, I did see the option in your photo and I had read elsewhere about the nozzle offsets but I did not know this ok for TAZ 5. Is there any way to adjust the offsets so that they are correct? I’m guessing it’s the window in my screenshot. Under the M175 tab, both the X and Y are set to 0.0mm. This is also true for my SE extruder under machine settings>hot end tab
Oh this is strange. The firmware updater said it was going to install v1.1.9.34, which is the latest version of firmware for taz 5 I think. After completing the update, when I go to the about printer screen, my machine says it has 2.0.0.144 installed. Also, when I connect to the printer in the monitor tab in Cura, I get an error dialog box warning of the Firmware mismatch. Saying the version in Cura doesn’t match what is on the machine. I tried it 3 times, and keep getting the same result. I’m using MAC OS by the way.
The nozzle offset change between v1 and v2 was to put the nozzle in the same place so when you were doing nozzle wipes and hitting the zeroing button and corner washers lined up.
There’s none of this in the Taz 5, so no need to worry about it.
So long as you have the right firmware on your Taz 5 so that the steps/mm and extruder power settings are correct, it should work fine.
If your build plate is mechanically in off a bit such that X0Y0 is off the build area of the build plate, you can mechanically move the build plate, or use M206 commands to adjust it.
Hehe, I don’t think it is the right firmware. see my previous reply.
For some reason, they stopped updating the Marlin 2.x firmware included in Cura, and cura won’t automatically update from 1.x to 2.x (or 2.x to 1.x).
For the Taz5 there’s little updated in the firmware anyway, since the updates centered on things with bed leveling, nozzle wipes, etc. If you still have 2.x firmware for the M175, keep that and ignore the warnings.
Cura 3.6.40 still had firmware for Taz5 w/m175 - Marlin_TAZ5_M175_2.0.0.144.1_ffaa466.hex.
Not sure what versions of CuraLE 4.x have that firmware in it.
Well it certainly seems to be printing well, better than the SE. Thank you again for all the info.
