Hello,
I currently have an LR2 and I would like to add endstops to make an automatic homing.
I would also like to have a tiny tuch plate
I’m sure mini-Rambo, should I change my card? If so, which one should I use?
Should I continue to use Marlin or switch to GRBL?
I’m not very good at electronics, so if anyone would be so kind as to be able to guide me through this, please let me know.
Thanks so much
The mini rambo runs two motors off of one motor driver. So it can’t possibly auto square. If the board has 5 drivers, it can control each motor independently, which will let you auto square the Y and Z on a low rider.
The jackpot is a great board that runs fluidnc (which is closer to grbl than marlin and has more CNC features). I would recommend that.
Do you know where you will install the endstops? I don’t think the LR2 had endstop mounts by default. I know there were some mods to add them. Ideally, you want the Z to home up towards the endstops for autosquare and probe down for the Z probe.
All right, I’ll change to a Jackpot
There’s no provision for Endstops, but I’ll find a way of installing them without any problems, I think.
I’ll get back to you with the details once everything’s installed 
Do I need to update the firmware for Endstops?
If I have my Endstop in Z, is the tiny tuch plate useful?
The jackpot is set for end stops and touch plate.
Yes, because Z homes up, the touchplate locates where the workpiece is (down).
ok good Thank you so much !
