  • Custom. It started life as a tronxy x5sa-400 but I think only 2 steppers and the frame are original still. I changed the bed to a 16"2 *3/8 thick aluminum tool plate about 5 years ago. It always worked well for me. Unfortunately the silicone mat I used doesn’t seem to be made any more. I’m going to try one meant for a creality cr10 S4. I may have to re-machine the mounting holes for the thru holes on the mat tho.



  • I got tired of windows updates breaking my dual boot. After some research I found that it’s possible to have two uefi partitions: one for windows and one for Linux. It’s not standard but there is nothing expressly written into the efi spec that prohibits it. And it just works. My bios doesn’t care, and works with them both just fine.

    I only use Windows for that 1% of business stuff I can’t accomplish in a vm under windows. Invariably after I boot into widows once ever 3 months it installs so.e update and would kill my ability to boot into Linux. Since setting up 2 partitions I haven’t had this problem.


  • I don’t have an iPhone but my daughter does.

    For music I don’t sync anything to her phone. I run a navidrome server and set up an account so she can stream whatever she wants whenever. I think she uses isub as her streaming app. It does allow you to download and cache files from the server to play if you are offline

    As for sms, I don’t know of any way to sync in Linux, but if you use Windows, the phone link app works, as several of my coworkers have set it up. I know it installs some piece of software on the iPhone you want to sync to, maybe you could do that and try running the phone link program with wine?

    I also know kde connect has a link for iOS. It’s not perfect but it will do the sms linking thing.








  • 31 days of perfect health and then drop dead? Or 31 days of slow, debilitating, crushing agony and pain and then death? I just lost my best friend to perotineal cancer, from diagnosis to her passing was 97 days. She made plans to travel with her daughter, spend time with friends, write a will, etc. but she ended up spending a majority of that time in the hospital on heavy duty narcotics and offer her nut because of them. I don’t think anyone would plan on spending their last 31 days like that but it’s more realistic.

    Tldr: do the things you would do with news like this now… Don’t wait until it might be impossible.


  • It’s easy to get out of hand when modding your printer. When I first got my tronxy in 2017 or 2018 the only planned mod was to put a duet 2 clone in instead of the garbage chitu control board. But the extruder sucked as well. Clone slice mosquito fixed that. Then I realized the extruder drive had a 700mm Bowden to the print head, and I wanted to print fast, so I asked Santa (my wife) for a zesty nimble (this was years before the orbiter direct drive). I had 3 vslot wheels disintegrate in a week and voron was using a cheap but high quality linear rails so why not? Then I built a couple of industrial kit printers for a friend, modix and raise3d. They weren’t much more complicated then what I had, and I’m learning some cad so I designed a quad z system with rails and smooth rods like the modix. I had another fried edm machine part of the z sleds. It was so over engineered that I needed to put a bed worthy enough in top and that was the 400mm 3/8" thick tool plate. A heater to match, 400mm ac bed topped with 1/4’ borosilicate glass.

    This took time over several years. I would grab my z motion control and publish it somewhere because it’s pretty simple but very effective.

    Anyway… It has been a lot more fun and educational modding the printer then making silly doodads and fidget toys with it for sure.


  • Perfect! I will read through the site for some insight.

    I didn’t change the extruder, I just changed the driving motor. There is the chance of backlash because of the way the drive cable works. I suppose it could be wearing out … or I am getting a lot of back pressure in the mot end causing it to slip. I plan on taking apart the nimble and replacing the bearings and relubing everything tonight or tomorrow. Plus a pid tube, if I am running too cold or something. Duet has changed their pid model several times and I haven’t retuned it in several firmware upgrades



  • I got the zesty nimble v2 as a Christmas present about 6 months after it came out and loved it right away. It is a remote direct drive extruder. It weights almost nothing and I can print pretty fast. Unfortunately zesty tech seems to have gone out of business. I had a beating on the worm gear go bad once… Maybe it has happened again as well… I think I have some extra beatings lying around so maybe I will swap them out again as well, in case it is getting hung up internally or something.




  • I do use a micrometer to measure, tho not a super .expensive one … I have found it to be pretty precise

    The zesty nimble is crazy gear reduction. On 16x micro stepping on a 200 steps per rev you start tuning at 1800 steps per mm. The gear ratio is 30:1. Because of so many steps per mm I have my extruder motor running at 525 milliamps… It really does effect extrusion, per recommendations. I can go lower if I raise my printing temp but then I get stringing. Anyway…

    I designed my own bed movement using 4 linear rails and z-screws and it was suggested to me that the spring couplets maybe causing the issue. I ordered 4 solid couplers to see if it is a backlash issue.
