Re: Which Thermocouple to buy ?

Using a thermocouple will require modifying the firmware and wiring. I've done this on a pre-V3. Basically you have the thermocouple, which has a 'polarity' and must be wired the right direction, it goes to a signal amplifier board, and then you connect power ground and signal wires from the amp to ...

Re: Possessed Printer

Does that dip in temp between 21-26 minutes correspond with when your cooling fans came on?

Re: Water cooling questions

Nozzle apertures at or below .2 mm Work with materials such as PEEK, PEI, or other engineering plastic filaments, where the cost of a failed print is high, and post processing the exterior is insufficient remediation. Can you expand on those? Why does water cooling aide smaller nozzles or improve p...

Re: Water cooling questions

It's a lot of cost (like you mention) and an increase in parts count and complexity to address an issue that very few people actually have. Air cooling works just fine except in heated chambers or at super high printing temps. Plus, the cooling block and plumbing (and the coolant) would add inertia ...

Re: Fuse keeps blowing

It's hard to fix the issue if you don't know which wires are which. Figure that out, and what's going on will likely surface. The hotend fan runs all the time, so trouble with those leads could cause a short instantly without having to turn on fans or heaters... Seems like a good place to start trac...

Re: Formlabs form 2 prints for members

Hey Justin!
I've got a handful of other resin printers, and know a few people with a collection for testing, so I might have you make some test/calibration pieces to compare and contrast them sometime.

This is the hot model, at the moment. https://www.thingiverse.com/thing:1219068

Re: High spots between towers.

Mark the glass, and index it around. Does it follow the glass or the machine?

Rotate your XYZ motors and endstops all over 1 position (YZX instead of XYZ if that makes sense) and see if it follows the mechanics or the electronics.

Re: Ferrite Beads Yes or No

In somewhat related topics... Don't tin any wires that aren't explicitly solder connections. Crimping pins on to tinned wires will lead to failure, and so will putting tinned leads into screw terminals. All of those connection types rely on compression and copper's malleability, which isn't the same...

I designed the original part (this is a remix for the ball-socket arms) and have been using an ABS one for a long-long time. I've never seen melting and burning like this on mine. What temps were you printing at?

Making custom colors on demand seems appealing instead of keeping a spool of every color on hand.
Also, buying plastic for $1 per pound is a nice prospect.
