Yeah, that’s the X Carriage I’ve been using. it works great, and having a removable “quick fit” extruder is really handy. Bam (one of the lulzbot people) also made a stabilized “official” upgrade carriage for the AO-101. It’s not quickfit, but it is an improvement over the one your unit probably came with. https://forum.lulzbot.com/t/ao-10x-x-carriage-mod/273/1 The 3 bearing vs 4 bearing argument is compelling. Eventually, after I get a few of the more immidiate projects finished, a carriage modification based on that one will probably be what I end up using, but with a quick fit component and modified for an auto bed leveler arm and a fan
My machine started out life as an AO-100, so it has the older style nozzle and RAMPS controller, so it will look a little different than your AO-101. That being said, i’d be happy to put up some pictures of my machine. Basically anything that isn’t printed in black is a replacement part. If you want more detailed pictures of a certain angle or whatever, let me know. There’s also a ton of pictures in the development section of things in progress that aren’t actually on the machine yet.
You should also take a look at the lulzbot HQ pictures and some of the configuration they are seeing on their machines. I’d hazard a guess that my machine is one of the more modified AO-100’s around at the moment aside from the one that makes pizzas, and most of the modifications I consider to be overall improvements in general, but some of the things like the removable extruder piece you will want to ask yourself what you want to do with your machine going forward. Is dual extrusion something you plan on attempting? if so, you might want to go with a dual extrusion plate from the start even with just one extruder, etc.
Modifications I have done to this machine from stock AO-100:
1 Upgrade all parts to AO-101 standards except the control interface and nozzle
2. 60mm height increase
3. reinforced Y axis motor mount
4. Quick fit compliant extruder and X carriage
5. RAMPS cover (not applicable to your machine)
6. The Taz style X ends
7. Widening the entire machine to mendelmax 1.5+ specifications to have room for the wider quick fit x carriage.
8 Swapped out the entire Y axis mechanism for a trinity labs linear rail, single layer plate, and much beefier Y axis tensioner
9. DIY spool mount out of PVC pipe and aquarium tube leftovers
Future upgrades in process:
- Adding a linear rail on the Z axis
- Sheet aluminum top deck plates and covers for the Y rail to prevent things from falling into them (mostly done, just waiting on mounting hardware)
- Moving the power supply under the chassis in the empty space where the Y rods used to be
- Adding feet to the frame
- Theoretically moving the RAMPS controller under the frame and re wiring everything using cable chains, but thats going to be a pain
- Adding the ring light and the gantry lighting, as well as a dedicated fan to the machine chassis where the power and RAMPS controllers are
- Addding the quick disconnect to the extruder wire harness
- Finish enslosing the sides, front and back with aluminum plate. Possibly a belly pan too,
