Good catch on parts cooling fan. Firmware "should" catch any broken thermistors.
Don't lube the Z lead screw, it's a POM nut and the grease will just turn into an abrasive paste when dust is added.
Belt tension is a science, Prusa makes a tension gauge available on prusaprinters. There are also a number of phone apps that will let you tune it to about 100hz.
The problem with firmware catching it is that it kills the print, and the time/power invested. I'd like to catch those before I commit.
I'll keep lubing the Z screw for now. It's been a problem for us in that a dry screw produced banding on models. The lube fixed it, but it can be hard to pinpoint these things over 1,000 prints and some variables I have yet to isolate and bring under my control.
Do you have a link to a belt tensioner? I'd like to check into that!
@UCeFd8y8A7xPR3ntl27eDJ2g Neat! I'll try it out. I like the idea of cutting down the time on monthly maintenance for this check.
Ahhh yes, you got the Lowe's in house brand compressor at "the home depot".
D'oh. Good catch!
Prusa's maintenance instructions specifically say not to apply lubricant on the leadscrew and go so far as putting a big red X over it, so I'm confused. Is the leadscrew eventually something that you need to apply lubrication to? Also, is it worth getting 3-in-1 oil over using the supplied lubricant that prusa includes with the printer on the smooth rods?
Over time I was observing compressed Z layers on my prints on about 1/2 of the army, and a bead of the supplied lube fixed it. So far I've had to replace 1 trap nut, and I have another that failed this week. I would imagine 3-in-1 would so the job as well.
I noticed this warning as well, but a couple months after running the printer heavily, I was getting hella squeaks and banding. Lubing the leadscrew solved this instantly
Nice
Thanks
Any special extra steps you need to take for the Prusa i3 mk3s? Or would the maintenance routine be pretty much the same as the Prusa Mini?
It's pretty much the same, but I add a z-cal to the routine.
Hi, I did the e3d v6 upgrade on the original Prusa mini. I have some expertise with 3d printers but I can't come up with a solution for the HotEnd clog even with the upgrade. I really don't see where the problem is, I unmounted and mounted so many times, all the phases for mounting the heatbreak are ok but the problem still occur. Can you make a detailed video on how to make this upgrade? And I would like to see the settings on Prusa slicer too. Thank you very much, good job
If I find myself adding more minis to my army I'll be sure to catch it on video this time!
Honestly, switch up to the e3d Revo, it's expensive, but it's an easy swap and no more clogs since I've upgraded. The heatbreak and nozzle are all one piece.
Bondtech heatbreak installed, not one clog since. Been months now.
Awesome video. A couple of questions?
Have you shared the cable chains anywhere?
Are you using the filament runout sensor? If you are, and since you are (I think) using the Bondtech extruder. They have come out with a mod to integrate the filament sensor in the extruder instead of hanging off the extruder.
Love your work!
