Trying to get My Taz 6 working with Slicer Help Please

I have my start script when I run the gcode from slicer for my Taz it grinds I quickly found some Machine limit setting that when I compare Max feed rate for x it was set to 9000 ive reduced a lot of the setting but cant save them I get a message

Cannot overwrite an external profile.

 

how can I achive this or is it not allowed if this is the case could I delete the start g code  that slicer has added

M201 X9000 Y9000 Z500 E10000 ; sets maximum accelerations, mm/sec^2
M203 X500 Y500 Z12 E120 ; sets maximum feedrates, mm/sec
M204 P1500 R1500 T1500 ; sets acceleration (P, T) and retract acceleration (R), mm/sec^2
M205 X10.00 Y10.00 Z0.20 E2.50 ; sets the jerk limits, mm/sec
M205 S0 T0 ; sets the minimum extruding and travel feed rate, mm/sec
M107

 

help appreciated

This is a Prusa forum, not a Taz forum.  Not too many us own a Taz.

You cant overwrite a built in profile but you can save a new one with whatever you like in it.  

And just because its not a prusa doesnt mean you cant use Prusa slicer.  I have profiules for my Mk3 and my much modified Cr10s.  Persoanlly I dont know the max feedrates for the TAZ but if you have a profile in something like Cura its possible to transpose the settings over to at least give you a reasonable baseline to start with.

I have no knowledge of the Taz, but we've had a few people configuring PrusaSlicer for use with other printers, and you seem to be on the right track getting the right values for the Machine Limit settings to start with. Unfortunately, you'll just have to hunt those down for your printer. If you're using another slicer with it successfully, you might be able to cheat a bit and examine the gcode it generates, then compare any M201, M203, M204 and M205 lines.  Other than that, set the bed size and origin correctly and you should be close. Keep an eye on the startup gcode to make sure it doesn't try to print the prime line in an illegal location or other simple problems.

RE: Trying to get My Taz 6 working with Slicer Help Please

@robert-h31

You and I are working on the same thing. I'm (slowly) working on a profile for the Taz6 and then TazMini at my local library's Maker Lab, both with the Aerostruder. My first attempt got similar grinding noises, so we may be in the same boat. I only have time to go over there for a couple hours each Monday evening (if I don't have to stay at work late).

I printed out a sample gcode of the same thing with as near identical settings as I could from the LulzBot Cura edition that is currently used at the Library and with my first attempt at a Plicer profile. The Plicer generated gcode has the grinding noises, but the Cura generated gcode prints flawlessly. I see in both that only the Plicer generated gcode the machine maximum settings are sent to the printer in the gcode. I have some screenshots of the Cura settings for the Taz6, but apparently I missed the maximums. I'll try to see if I can find the machine maximums in Cura on Monday. If anyone is curious, here are the two gcodes that I generated: SampleObjects

RE: Trying to get My Taz 6 working with Slicer Help Please

looks like the PS speeds are much higher. look at the F values

the cura profile has a bunch of start G-code differences

the purge line extrudes a lot more in the PS g-code

Yes, I'm quite sure that the max speeds/accelerations in my Plicer profile for the Taz6 are unreasonably high. That would explain the grinding noises as steppers are driven faster than they can physically go so they start skipping steps. Hopefully I can find reasonable values tonight.

RE: Trying to get My Taz 6 working with Slicer Help Please

Here's one noticeable difference: 

M201 X9000 Y9000 Z500 E10000 ; sets maximum accelerations, mm/sec^2
M204 P1500 R1500 T1500 ; sets acceleration (P, T) and retract acceleration (R), mm/sec^2

vs

M204 S100 ; set probing acceleration
M204 S500 ; restore standard acceleration

 

ps: and this seems high for even a Mk3: you may want to slow these figures way down, or omit them.

M203 X500 Y500 Z12 E120 ; sets maximum feedrates, mm/sec

The wipe section is being done much too fast for the TAZ - at least compared to how the Cura slice reads.

RE: Trying to get My Taz 6 working with Slicer Help Please

I achieved success. My profile might not be perfectly dialed in yet, but I can get prints from it without any grinding noises. I couldn't find the details I wanted (printer maximum speeds) in the Cura 3.6 (LulzBot edition) interface, but someone in the maker area mentioned looking for the json Cura settings files. After digging through the filesystem, and following includes (I forget the exact term, but similar to #include statements in programming) I finally found the values I needed. Here is a config bundle that has the Taz6 w/ Aerostruder (0.5mm nozzle) printer, 0.3mm layer-height print, and ColorFabb PLA/PHA filament profiles for anyone else to use as a starting point.

PrusaSlicer_Lulzbot_config_bundle

One possible enhancement is to add a purge line. Cura doesn't use one so I didn't add one, but I was noticing that it would take a bit to get filament flowing so I upped the skirt to 3 lines wide.

Odd, since the only changes I made in the start g-code was to change the variable names from Cura format to Plicer format. (Including fudging some numbers for the wiping hotend temperature that Plicer doesn't have a variable for) Everything else in the start g-code (and end g-code) is a direct copy from the Cura 3.6 LulzBot edition that is installed on the library's computer.

RE: Trying to get My Taz 6 working with Slicer Help Please

Depends on the default acceleration of the TAZ.  In the PS code it's set to 1500, then after wipe it is set down to 500.   In TAZ it is at default until after wipe then set to 500 with the comment of "restoring it to normal".

RE: Trying to get My Taz 6 working with Slicer Help Please

Right, and I fully accept that I didn't have my default accelerations set properly. See the post above from tonight with the new profile that I came up with. It printed fine on the Taz6.

But, I fully admit that it is only a working starting point and may not be tuned optimally.

RE: Trying to get My Taz 6 working with Slicer Help Please

Oh, I forgot to mention something about my profile posted above. I used a custom bed model for the Taz6, and that file exists in the installation folder for Cura 3.6 LulzBot edition on Windows. Specifically:

C:\\Program Files (x86)\\cura-lulzbot 3.6\\resources\\meshes\\lulzbot_taz6.stl

I'm not sure what will happen if trying to load that profile on a computer where that path doesn't exist. I don't know if Plicer will give a warning, silently ignore the error, refuse to load the profile, or reverse the expansion of the universe to eventually culminate in the Big Crunch. If you have problems loading the profile on your computer, remember the Plicer configuration .ini files are text files, and a quick run through a decent text editor should allow you to delete the problematic path on line number 225.

Oh, I has also forgotten that I had created a filament profile for PrintedSolid's Jesse PLA (re-discovered that while looking for the above path). Neither of the filament profiles are really tuned that much, so use at your own risk (or manually delete them from the profile before loading into Plicer).

You need to zip then upload files.

I was looking for the same support and stumbled across these links

https://www.reddit.com/r/lulzbot/comments/evgorw/prusaslicer_profiles_for_taz_printers/

Which led me to this

https://github.com/jjaeggli/prusaslicer-lulzbot-taz

Looks like a good source and  I will be testing the profile in the coming weeks.

RE: Trying to get My Taz 6 working with Slicer Help Please

Here are the profiles that I made for the Library's printers, a Taz6 and a Mini, exported last night with the latest tweaks applied since my last upload further up this thread. Both have a single extruder Aerostruder, 0.5mm nozzle.

PrusaSlicer_config_LulBot_Mini&Taz6

I also included the bed stl files for the Taz6 and Mini as distributed with the LulzBot edition of Cura. Note, the stl for the Mini is off-origin. I had done it before but that file got lost on a laptop refresh. I haven't gotten around to moving the origin again, but I think it did it easily in MeshMixer. (I just forget off the top of my head how much to shift each axis...)
