Bumping so I can install that linked fuse above asap. Sorry for the 2 filler posts, misread the fuse stats on mouser and asked crazy questions in light of that!by clearlynotstefan - Duet
Would this work? this fuse doesn't specify ac or dc but is fast blow 250maby clearlynotstefan - Duet
Also, what happened here is symptomatic of a blown VSSA fuse right? Everything is fine except both thermistors throw faults.by clearlynotstefan - Duet
I THINK I know where you'd connect the cartridge fuse according to your instructions, wouldn't that leave an incomplete circuit where the F1 fuse is currently? Or do you bridge that with solder if you go this route. Would you be able to share the specs of the fuse that I could wire in between thermistor+ and endstop GND? I'm thinking I'll go that route. I'm entirely positive it wasn't a cartridby clearlynotstefan - Duet
Hey all (/DC42), I've been working with a new SSR switched mains powered aluminum heater attached to my aluminum heat spreader. Took me a good while to get the PID tuned perfectly. For a few brief moments I was able to warm my bed evenly and to the exact temp I wanted! While cutting down a sheet of PEI to affix to the new setup, and not touching the printer, both heaters started displaying faulby clearlynotstefan - Duet
Haha I have gave up a few hours in assuming it glitched out. In cases where it takes hours, does that time usually take place in phase 3?by clearlynotstefan - Duet
For reference, the heater I'm using is similar to this, but roundby clearlynotstefan - Duet
In my unending impatience, I've started using an aluminum heater under my heat-spreader while I wait for an appropriate silicone heater from China. Alls well, fits perfectly, certainly gets hot, heat dispersion is the clear weak point, but thats what the heat spreader is for I suppose. Only problem is the default bed settings are def no good. It takes a few seconds to get cooking, but then it soaby clearlynotstefan - Duet
My delta currently uses a 8mm thick aluminum tooling plate with a circumference of 300mm. It's a big, heavy, very flat surface that my glass bed sits on. I'm going to be experimenting with the FSR kit from ultibots later this week, which includes the silicone pads and I have recessed mounts and all ready to go, but most people are using much lighter heat spreaders with them. Anyone have experiencby clearlynotstefan - General
Dc, did you ever get that post out? I still can't get a good first layer down across the whole bed, and I've made further mechanical improvements to boot! I'd love to hear all the things mentioned in your post above! Thanks for everything!by clearlynotstefan - Duet
That sounds like a slicer issue, not a machine issue if your steps per mm are ok. Forget z hop and fancy stuff for now. Enable display travel moves in your slicer and flip through the layers to see if your machine is merely doing what it's asked.by clearlynotstefan - Delta Machines
I've deff seen people wedge the fsr against the hotend somehow and use that. I get excellent repeatability with dcs IR probe, it just needs to be offset which makes effector tilt problematic. To me the ideal setup would be 3 of them mounted in a triangle around the nozzle, probing till all 3 register then averaging the results. Peru pretty sure you'd get height at the nozzle but haven't thought iby clearlynotstefan - General
My delta build is currently in um... Alpha. Was battling effector tilt while battling calibration/bed leveling issues, ended up ordering new horizontals that aren't here yet so I can't say for sure how it lines up to the DC42 IR magic, I did manage to probe the aluminum bed accurately and repeatably and generate a height map that seemed pretty solid. When I get it put back together for real I'd bby clearlynotstefan - General
Yup, couldn't use it every day mostly because printing on clean aluminum is annoying, the nozzle thing didn't seem to come up. The reason I was interested though was more to compare it's accuracy with my other z probe during delta calibration and if terrible to use the difference to measure effector tiltby clearlynotstefan - General
nvm got it working. Easier than I expected!by clearlynotstefan - General
Would it be possible to create a low volt circuit between the nozzle and an aluminum bed itself? Not FSR, but basically a setup where your nozzle closing the loop by contacting your bed is treated as a NO switch?by clearlynotstefan - General
disregard, just stripped one, they're wayyy thicker than I thought, won't be a problem.by clearlynotstefan - Delta Machines
Oh you just reminded me! How do I extent these tiny thermistor wires?!by clearlynotstefan - Delta Machines
My big custom delta will have a heated chamber and a serious 500w 12x12 silicone heater attached to a 6'm tooling plate that radiates heat. The bottom end of this thing is cooking! On top there are a few layers of glass and air before the top panel which has the electronics and such. I was just getting ready to manually extend my stepper motor cables when it hit me I cam just put the motors up toby clearlynotstefan - Delta Machines
Woooooo! Odd, that it'd happen at the same height but with different xy positions seems very weird to me.by clearlynotstefan - Delta Machines
The fact that it offset by the raised bed narrows the field significantly. Sadly that almost makes it worse, as it rules out most of what I thought it could be! Localized Mechanical binding and carriage issues wouldn't do it. The carriages only have to move 50mm in unison to get past your trouble zone, but much more to try the print on the other side of the bed.. If it was a troublesome area of vby clearlynotstefan - Delta Machines
Is that red peak -x? I have no perspective on itby clearlynotstefan - Delta Machines
Challenge Accepted, I'd love to be wrong here, but I bet you something is fishy in the visual representation, which of course doesn't REALLY prove anything because a mechanical problem could cause effector tilt or poorly located probing points etc, so a messed up bedheight isn't that probative, my thought is something is causing the bed height to be off, which throws off autocalibration which exby clearlynotstefan - Delta Machines
While you're at it enable bed probing and try the new height map visualizer. I'd be so curious to see how it does or doesn't line up with the symptoms. The ability to see what the printer sees is awesome!by clearlynotstefan - Delta Machines
Just for fun, have you tried actually running the new auto bed level feature? I'd love to see the height map it generates, it'd be useful for us to know what the duet is seeing when it probe the bed. The newest version will generate a visual display you can post here, peep DCs post in the duet forum!by clearlynotstefan - Delta Machines
The fact that it is moving in exactly a -X direction, aka not towards or away from a tower, and is so consistent and reproducible isn't enough to overcome the doubt raised by swapping motors tho? I can't think of a single non-digital error that would move all three carriages just right to skew a print along the x axis reproducibly. You also raise a solid point about swapping motors not changing tby clearlynotstefan - Delta Machines
