Cohesion 3d Mini bootup Issue

Installed Cohesion 3d Mini within a custom built Laser Engraver.
Actually purchased a K40 but just salvaged it.
Had bigger and better things in mind, so i built my custom
340x640 laser engraver…

Anyhow, i have an issue on power up. It does not want to power up right away.
I end up hitting reset like 3 times. 2 times to actually get the Mini to fire up and start running, and
another to get the LCD to initialize.
Component wiring:
I have external power supply 24VDC - 5Amp powering the mini and the aux emergency stop and safety door circuitry.
I have external 36Volt DC power supply for external microstepper drives.
I have external power supply for ventiliation fans…

I have used the breakout boards for controlling my stepper drives.

The firmware installed in Cohesion is the Cluster Firmware.

From Lightburn readout:

Build version: edge-54d22942, Build date: Jun 5 2019 14:09:26, MCU: LPC1768, System Clock: 100MHz
CNC Build NOMSD Build

Here is my config file…

after getting it reset and running, i tested the Lightburn software and results look good…
Still haven’t burned anything…Waiting for chiller and some more guard work needs to be done :frowning:

Hi Russell,

Welcome to the forum! Congrats on your custom build.

Please provide pictures of your machine, board, other electrical components, and wiring. We’ll need to see these first before troubleshooting the boot up issue in depth.

Have you run cluster firmware and it worked successfully before?

I’ll elaborate on the other parts of your post once we hear back with more details on your machine.

Bad eyes hooking up my kill switch…For some reason the Kill switch contact was open. When this is open, the board does not boot properly… Does this seem right ?

Hi Russell,

Yes, that is the connector for the kill switch.

Is it NC or NO operation?
Couldn’t find any documentation on that…
Thanks…

Hi Russell, I tested my Mini and it’s NO.
