Latest Firmware for TAZ5 - advanced development version

Look here for custom firmware, networked 3D printer hosts like OctoPrint, and more!

Ya, I don't have an enclosure and the printer is in a spare bedroom where it's 76F. Also no need to wait for it to cool down. It's definitely fried. I actually heard the noise of it frying a few rooms away.

Now I just need to decide if I want to spend $220 on a new RAMBo board or a different board like the Azteca X3.

btw I don't want to sound like a fanboy but this firmware has totally fixed my printer. I had corrected all the mechanical issues of the Taz 5 but was still getting substandard prints when compared to my Makerbot R2. Both printers have been heavily modified to correct all their mechanical faults, but while my R2 prints are perfect my Taz prints always had strange issues, with warping, bulging at corners, overhang issues and problems with retraction, just to name a few.

Since updating to this firmware my Taz 5 is now printing better than my R2 and believe me the R2 prints amazing. I am getting really good prints now out of the Taz 5. Finally after a year and a half of banging my head against the wall. This bugfix branch needs to become standard for Lulzbot. I hope they are paying attention.

ps I am using the standard k values for PLA on ABS and it's perfect.

Hmm, maybe it's time for me to try this one. I kind of don't want to redo all the blinky light modification firmware stuff in it though heh.

You might try it first without your mods and decide afterwards?
There is a chance that this feature will be merged into the next official Marlin release, so maybe you also want to wait for your mods until this comes out. Nobody can tell when this will be, but I think it will be this summer..

I'm not a basic user for most things but I've only been in printers for a couple years and haven't dived much deeper than changing everything (really everything) in my slicer, a bit of gcode, and some soldering on a previous printer.

Is this firmware ready to be a daily driver with only undiscovered bugs, or a development version with things that still need to be fixed?

Seeing your photos and other users' testimonies I really want to upgrade because I feel like my Powerspec 3D put out better prints than my Taz 5 that cost 3x as much. I'm not afraid to get my hands dirty but I don't want constant issues. Thanks for all the work you've put in on this you wonderful human being!

This code is based on a marlin release candidate, so there will be some smaller bugs. But i couldn't find one since I'm using this versions, in most cases they happen with printers using Corexy setups or bed leveling.
I'm using it for daily printing, but just have a copy of your current firmware on you computer. If you see some bugs, you can restore your old firmware within 3 minutes. :)

I'd already installed it, I just got too excited. Good to hear though!

I'm on my 8th 20x20x20 cube, the first 5 were calibrating before the update. Post upgrade there was an immediate improvement, the only thing I changed was my z offset by +.01. I'm currently testing FW retraction with Simplify3D, I've found out that retraction must be checked and the following has to be added to the "Additional terminal commands for post processing" under the "Scripts" tab:

Code: Select all

{REPLACE "G1 E-1.0000 F6000\n" "G10\n"}
{REPLACE "G1 E0.0000 F6000\n" "G11\n"}
{REPLACE "G1 E0.0000 F1800\n" "G11\n"}
Cube 6 is the first one printed after the update, these pictures aren't really doing it justice. I ended up at 50mm/s and 30% speed on the last outline loop which probably isn't as important with the advance feature, but prints are turning out nice. after a few bigger items I'll play with making it quicker. Pardon all of my notes on the cubes, I was keeping track of my changes.

One note to the k values (remeber it can be changed with a M905 Kxxx command), I have a new value for nGen so to have a complete list valid for a TAZ 5 stock extruder and simmilar ones:

PLA: K=75
nGen: K=150
ABS: Maybe in the range of nGen?

Retraction can be very low with this feature enabled, I'm using 0.5mm for nGen at the moment.

Hi!

Just gave the FW a try. Don't mean to be a pain - just a couple questions.

Having an odd issue where the extruder stepper is making a loud clicking sound and vibrating when the print head goes around curves. I'm attaching a movie. You can hear it well when it gets to the third curve.

I am also experiencing a second problem. The extruder makes odd movements beyond the bounds of the print while printing.

One last small issue. Gaps at Layer starts. Especially on perimeters.

Thak you for your hard work :)
