Re: ABS juice for PETg bed adhesion

I use PEI and PETG without too much issue. Don't squish the first layer. Bed and 70 -75C for small parts and 80C for larger parts. Pop the plate in the freezer and they release fairly easily.

Re: PEI print bed surface experiments

I've been using PEI for awhile now... awsome stuff. My question is autocalibrating with FSRs while the hot end is at 250C. 250C is above the glass transition temperature of the material. The touch is very brief, but I didn't know if anyone had long term experience with the effects of probing the sur...

Re: 6ft tall Rostock Max build!

Belt spacer clamps are not used with the TrickLaser brackets.

SeeMeCNC belting is thicker than some others and works better. If needed, a few layers of kapton tape or some other type of shim material placed in the slot will increase the clamp pressure.

Thanks! Did you use the latest FSR versions that don't overconstrain or did you use the solid mounts?


I did the solid ones but had them milled in aluminum, polished them and put some gun oil on to make sure I get smooth movement


Wow... those should look slick.

Re: Trick Laser MAX METAL Build

I'm been picking at a few improvements. I've added a new heated bed insulator bracket (version 3) to the Git Repo. This version allows use of an unmodified snow flake and moves the mounting to the corners of the frame. It will accept a 4-40 nut underneath so the original screws may be used. I pushe...

Just clamp it down with the glass. Make sure you keep the film size against the PCB to prevent shorts.

Re: Mostly Printed CNC Router

Not sure about what material you are using, but I am finding PETG is much tougher than PLA and resists layer separation.

Re: Rostock MAX METAL - First Build (Attempt)

I'm impressed with the friction weld approach you took on the trucks. Once the belts are tensioned, there should not be much stress on the spacer. I'm close to releasing the enclosure parts for the duet electronics. The first print exposed some clearance issues around the board that need to be addre...

Re: Trick Laser MAX METAL Build

Updated FSR specific mounts have been uploaded to the git repo. There were some height related issues that slipped in.

Everything appears to line up well. I will wire and test in a few days.

I believe you just use washers to space and center. Brian posted an update somewhere within this topic.

I can run 8mm retracts on PLA and PETG without jamming issue on my Prometheus. The long polished one piece barrel is forgiving for the long retracts.
