I have been really happy with the Biqu H2 extruder on my Tronxy X5SA-400, but had some issues with the mount for the CRTouch and on a print it actually got knocked out of place, caught the probe on the model, and bend the probe pin. When I went to get a replacement I found the Biqu Microprobe and figured that since I was already running a BTT board on the X5SA that their probe should work well. However, the Microprobe has a slightly different mount and since it was smaller I realized that I could mount it between the ducts on the Claw and have it directly in line with the nozzle for an essentially zero X-offset for the probe at only a slight increase in the Y-offset. 

When working on adding on the Microprobe bracket I decided to add one for an ADXL345 as well since it fit nicely. The holes on my ADXL are about 15.5mm apart- I know from experience they're not all the same, so you should measure and see that it will fit.

I've included versions that have both brackets and that just have a bracket for one or the other. 

On my setup, the offsets are:

x_offset: 0  
y_offset: -45

Yours will likely be very similar. Don't forget to adjust the other settings in your config to account for the change in the offsets. Also note: if you're using sensorless homing as I am, you should confirm that that brackets won't hit your frames- I had to adjust the stopper I have installed so that the probe bracket didn't hit the top front extrusion.

Since it sits close to the hot end it should be printed in something that can take higher temps- I used PETG. Either version with the Microprobe bracket will need supports; if you're printing the one with just the ADXL bracket you shouldn't need supports if your printer is well-calibrated. Only the probe bracket should need to be supported- the ducts should print without supports.

Differences of the remix compared to the original

Just added brackets to mount either a Biqu Microprobe, an ADXL345 accelerometer, or both.
