    No progress in the last few weeks, still waiting for the elusive motor couplers (oldham)
    I have received an LDO stepper around which I can build the HextrudORT extruder. A recent upgrade to the Ender 5 means I should be able to make it in ABS or PETG

    Tell you what, I recently got some Sunlu PETG, spent 4 hours this afternoon to get the first layer down. Nada, no go. Tried extruder between 220-250C, bed from 65-90C, no bloody luck.

    Ah well, will wait for my lazy Susan , should arrive tomorrow, then I can print my extruder from the nylon, Geoff. Was hoping to short-cut with the PETG, but will try that again on my HevORT at some point.

    So you’re still waiting for those couplers, hey? Chit, yes, I recall I waited months for mine as well. Hope it arrives soon, Mate, but it gives you time to sort your extruder bits out :)

    That sucks! I'm printing with eSun PETG at 245°, bed 80° on a cheap flexible steel sheet and it's going well. No problems with first layer and so far, no stringing. Last print was a bit difficult to remove support material so adjust a few Cura settings, hopefully this one will be better.
    I've got some eSun nylon on order so looking forward to trying that - must dig the humidifier out and finish the PID controller I started to build.
    I'm just going to have to put up with the wait for the couplers. I did look at some other suppliers but they were quoting Oct 22 delivery...
    I can get stuck into the base plat for under the electronics Plan is to get it laser/waterjet cut out of 2mm mild steel with cooling slots under the major components. I haven't gotten a price for this as yet so it's subject to change!

    EDIT: Just had a look at what I'm printing and it seems I forgot to specify support material Duh! Seems OK so far though.

    Finally the morot couplers arrived, so I can get back into the build.
    I'm a bit embarrassed to say, I have now found quite a few bits I could have made progress on :o

    Haha, true :)

    Great your bits are almost all there, progress will happen. Still battling that damn PETG, but guess what, got some Nylon-CF, that is almost as easy as the PLA to print. Also much nicer to look at, but man, those supports…..oopphhh…difficult to clean up.

    But found my new favourite filament, can’t wait to push it through the HevORT.

    Good luck with your build, looking forward to your progress! Craving black and yellow pix!

    Life gets in the way of the best plans but back to the Hevort build!

    JLC, the PCB manufacturers, now offer 3d printing at very competitive rates. Options include FDM, resn or MJF* . I've just ordered all the parts for a Hextrudort to suit the Mosquito hot-end, total cost with shipping $34.
    The online ordering process was a little confusing but with excellent help from their online support, got it all sorted. You upload an STL file and it's then reviewed by someone who gets back to you with any possible issues that might occur with printing it. MJF material used is PA-12 nylon either grey or dyed black. It's probably going to take about 3 weeks to get here (3 days for production)

    I did manage one monumental stuff up in that I ordered the parts to suit an MGN9 rail but I have an MGN12 rail in my build - old age catching up perhaps... :rolleyes:
    I've now ordered an MGN9 rail as it will be quicker and cheaper than getting the parts reprinted.

    *MJF works by using an inkjet-style process to deposit fusing and detailing agents to control voxels that are then fused into a solid layer then repeated until the build is complete.

    Parts arrived from JLC today. Very happy with the quality - fit and finish is very good.
    Holes are slightly oversize but nothing that will affect assembly.

    The belt adjusting blocks fit snuggly in place on the carriage without any sanding or filing.
