Been a lot of years since I looked at gcodes, and just checked the RepRap/Marlin list for the dwell code. The G...

Re: Anti Z wobble Z nut

Irony, I printed out the 4 nut holders last night, still have to do the bearing holders. And they came out with almost no banding due to z wobble. LOL. That's like when you bring your car in for service and it starts running perfectly. Of course I've had plenty of parts with wobble quite noticeable,...

Re: Anti Z wobble Z nut

Thanks so much for cleaning the STL's they look great, and I appreciate your help with the hardware. Just trying to get everything on order so I can do this upgrade in one sitting.

It's a fine design, and I much appreciate all your hard work.

Re: Anti Z wobble Z nut

Regarding hardware requirements, can I get more guidance on the 1/4" threaded spacers and screws? You don't say how long the screws should be or what diameter is recommended? I can get 1/4" threaded spacers with any number of different thread sizes, and of course I still don't know how long the scre...

Re: What should I actually expect from my TAZ 5 with minimal modifications

Thanks for the temp info for ABS. Based on what I've read on the forum I thought is was the lack of an enclosure. The room temperature where the TAZ resides varies between 59F and 67F (max); don't know what it was when the Benchy prints were made. Is the flex in the Y direction the Z mount itself o...

Re: What should I actually expect from my TAZ 5 with minimal modifications

Adding a third rod would stiffen things up and reduce the torque on the extruder carriage mount. I find a lot of the X carriage torque in the Y axis direction was due to the flex at the base of the extruder carriage. The taller extruder body with the upper mount, even on a stock Taz 5 removes a gre...

Re: What should I actually expect from my TAZ 5 with minimal modifications

What characteristics of the print help you see the temp is too low? I can see some things indicating my PLA being too high. Is there a place to visit that lists the types of things to observe? I'd expect different brands, and potentially batches. to need somewhat different temps so observing prints...

Re: My extruder mount is rocking!

Just ordered 3 12mm x 515 long hardened steel shafts, 6 linear bearings from Misumi. I am going to 12mm on the x-axis and adding another shaft in front of the extruder. I've had it with the X axis. I ordered 515 instead of 500 because that's what Mangrove is using (next Taz). So if it all goes to he...

Re: What should I actually expect from my TAZ 5 with minimal modifications

If I could change one thing on the Taz it would be removing the cantilever mounted design of the extruder. I firmly believe the true final answer to correcting the X-axis is to add a third x-axis rod in front of the extruder assembly. Make all three rods 12mm and use linear bearings or high toleranc...
