I want to upgrade my MPCNC. Including dual end stops, and a laser option (5V pwm).
Can I do his with the RAMBo Board?
or should I upgrade the board also
If I upgrade the board, recommendations?
Thanks
You can just load the latest dual endstop.firmware for the RAMBo and you’re good to go. So long as the performance has been good for you, it will remain the same.
You should be able to find the dual endstop version in the marlinbuilder releases page.
The specific one you want for dual endstops is https://github.com/V1EngineeringInc/MarlinBuilder/releases/download/515/V1CNC_Rambo_Dual-2.1.1.zip
Assuming you have a full Rambo board, not the Mini Rambo board, both endstops and the laser will work. I have a Rambo board, and I do a lot of laser work. Note There have been some test runs on the forum that indicate you can get faster laser engraving with newer, 32-bit control boards, so there is a bit of benefit to upgrading, but I suggest you just use what you have and upgrade later if you think you need to.
Thank you!
Thank you
I am struggling to upgrade. The link to the pre configured Xloader is broken. No joy with trying to configure it. Also read some where “dual end stops are wired normally closed? Is the true? If I try to use Arduino IDE , there are missing files. Also saw a post about modifying marlin.cpp file, can’t even find this file. I appreciate any help!
yes, V1 firmware expects normally closed switches, that is to say that they conduct between ground and signal, until triggered, when the switches stop conducting.
