Bed Level Probe question: When the bed level probe uses the Z-min-limit pin, is the z-min limit switch no longer needed? I'm developing an add on board with connectivity for the inductive probe, IR-Sensor and BLTouch.

Any of you users of these want to help me understand how these are set up?

For starters I know the inductive sensor gets connected to an optocoupler which works just like a limit switch to pull the line down to ground thanks to the Wiki, but I'm looking for confirmation that the BLTouch and IR sensor pull the line to 5v when triggered.

Another question: when the BLTouch is connected to the z-min limit pin does the BLTouch get used whenever the device is sent to home?

Anything else you can tell me or direct me to for detailed setup information would probably be helpful. 

For those that are interested here are the preheat test results on a ReliaBuild 3D Big with Dual heads (RBB3 Dual). This is using the new big heated bed PCB, 4E3D main board, ATX style power supply, and new cables. Used the default firmware PID's.

Preheat ABS: Nozzles at 230 C and Bed at 100 C. Max heating current draw test.

Nozzles both reach the 230 C temperature within seconds of each other at about 3 min and are stable. Very slight hover below the temp before zeroing in. With hand tuning this speed could be improved.

Bed reaches 60 C in about 6 min.

Bed reaches 100 C in about 16 min. Slowed down on final approach. Again with hand tuning this speed could likely be improved.

The results is still almost twice as fast as the old system for me.

As a side note I didn't have to make any nozzle adjustment when leveling the bed which only took 4 times around to get level.

And there they are, the first three next generation BIG frames. All out of ultra strong extruded aluminum. Light as a feather and tough as steel.

What is the best setup to do a dual extruder on the rigidbot? looking to do dissolvable support on a rigidbot big.

Excuse me, can someone give me information on the RB1 leadscrews? Are they regular 8mm acme lead screws?

Would anyone be interested in helping me connect some square holes to circles for a couple parts I want to print. I can send each one as an stl or skp file. I've been trying to figure it out but I can't and I want to try and print these parts by this weekend.Heres a couple screen shots for examples

Does anyone have a 2D cad file or STL file of the rigidbot bed? Not the Big bed just the regular size bed. I have a connection to someone that can machine a new bed for me either out of aluminum or stainless steel. The one on thingiverse is not opening correctly.

Got my Rigidbot big upgraded to a RBB3! The upgrade was a fairly seamless transition, back up a printing better than before. Very happy with the support and communication during the upgrade. I had my old heated bed cable start to melt, so I went a head and jumped in for the full electronics upgrade, happy I did.

What do you all think of this product?

Here is the latest video that covers the BLTouch sensor

The narration is done by +Tony Gomes.. Great work!!

I start to like the BLTouch.. Its small, accurate and light.
I think I prefere the BLTouch rather than my IR sensor.

Now i will continue with my RBB/MKS 1.4 rebuild with 12mm rods and my "box-extruder" . My new RBB will have graphite/brass bearings to be silent
