Hey Ohmarinus! How is the machine running now?
I am considering moving to single extruder and bowden-pusher instead of my extruder on the carriage. I just find dual extrusion such a pain to tune and 95% of the time I just want single head. Also, my glass plate cracked a bit (my own fault) and although it still works fine for now I am thinking PEI sheet is in order. What are you using for build plate?

would you like to share the firmware somehow?

On long prints, I'm finding it tough to manage the heat creap vs ABS warpage (and popping off the plate). It's like threading the eye of a needle temp wise. I'm strongly thinking of going in your direction with the bowden tube and external extruder. I added little tiny fans to steppers and no go. My other alternative is to convert some of my carriage to metal (I have the stock and CNC machine) and it will conduct the heat and radiate it better....or I can go back to water cooled which really solved this problem - like a fire hose! I really wanted to have dual extrusion and ninjaflex but right now I just want a reliable print. I just thought I could simplify by removing water cooling but with a heated chamber + buildplate keeping steppers cool is hard - even with fans.
Did you post the design for your carriage on thingiverse? I would like to give it a try if you don't mind.
Thanks,
Colin

Hey hey, well I would like to share it when it's finished! I'm actually going to convert it to print with PLA. ABS is just too toxic. So I still have to design and print a print cooling fan, but the biggest challenge is fitting it in with the current carriage design... One other change I'm making is that I bought this magnetic flex plate because sometimes the prints stick so well to the bed thatI can't get them off. So, I have to 'yank' on the bed and I'm afraid this causes damage to the motion system.
Maybe I'll get to it next week. If I manage to add a print cooling fan I might have to make some changes to the carriage as well. I didn't add mounting holes.. Which was a mistake. So I'll probably drill and melt in some threaded inserts to accommodate an additional radial fan. Let's hope one radial fan is enough. I will update once it's finished. Also have to convert back the hotend to use a PTFE liner instead of the titanium one that I have in place right now, I think titanium doesn't like PLA.

Ohmarinus, thank you very much for sharing!
I have just started converting my Replicator 2 yesterday and already found some helpful hints from your thread.
My setup is (or better will be) SKR3 v1.4 Turbo, TMC2208, TFT35 v3, BLTouch V3.0, ESP01S Wifi, DCDC MOD V1.0, BTMOS V2.0.
So far I replaced the connectors, integrated the TFT display and made all three axis + extruder move. Still a long way to go, but getting there step by step.
There are still some things which puzzle me with the Board and Marlin... But okay, nothing which cannot be solved :-)
- Limited number of PWM FAN ports.
- Filament runout sensor in Marlin only works with an LCD screen. Or if you set EXTRUDE_MINTEMP 0 and risk cold extrusion
- TRP is not enabled by default
PS: Always ground your electrostaticly active office assistant.
Cheers,
André

Interesting about the titanium insert. You and I are still putting the Experimental in "Rep 2X Experimental" aren't we! lol. I just went back to water cooled head, but this time minus the huge Koolance unit (for CPUs) and instead just a small 80mm radiator and what is basically a fish tank pump I think. All in all, cost me <50$. Motors sustain 10degC above room temp after hours so heat creep issue is definitely solved. I don't like the dual head anymore though, too heavy and a royal pain, I ordered an Orbiter V1.5 Extruder which will arrive this week. It's direct drive but lightweight. Hoping I can ramp up acceleration after.
Orbiter is a much smaller stepper with planetary gears and dual-drive filament gears yet still capable of fast acceleration and velocity.

LordOfTheBatch:
Any reason you didn't go with the TMC2209s? higher current ability (or less temp at lower currents) and serial setup (done from Marlin) is convenient.
Limited number of PWM is a big pain. They could have easily added a two more I'm sure.

Very nice to hear! I think these machines are great platforms to upgrade to open source. Everything can be fit in the box underneath.

The PWM FAN controls can be expanded, I created a DIY expansion myself as posted on page 1. If you want to know more, this is the topic about the PWM controller that I built, and it works really well:

That's a great looking extruder! I think direct drive works better than bowden.. My diy prusa has direct drive and it performs really well, but better than my old printer. Is that orbiter extruder also available as a bowden extruder by any chance?

Interesting thread to read through.
Do any of you who are converting machines have any left-over MakerBot electronics - dead or alive (or in between!) that you might be willing to donate to a project I'm running to create a drop-in Mightyboard replacement for the Rep2/2X?
I've just successfully restored several machines, but one was completely missing its motherboard and would be a good candidate for fix-upgrade - but I'm very keen to create something more plug and play and easy to... replicate...?
Cheers, Alex
