Gonna need a new heater something like this (maintain 24v supply) 16" X 16" 400 X 400mm 24V 200W w/ 3M JSR2 Kapton Heater Heating Pad Mat 200W will not put too much of a strain on the 15amp Ender power supply and a piece of 400mm x 400mm glass for the top and a piece of something for the bottom bed If you want it to heat up faster 120V AC heater and Solid State Relay to control it otherby cozmicray - General
Better to get laser with TTL trigger Power laser via 12V supply ON / OFF PWM via TTL Return it get a laser with TTL triggerby cozmicray - Laser Cutter Working Group

I have a CubeX Duo that I have not upgraded yet. Did you preserve the extruder PC board above and behind extruders It appears to have some components on it? Do these play well with other extruder drivers? why RUMBA and 24V?by cozmicray - Reprappers

Laser should be connected to 12V supply from DZT 's Store website ---- PWM/TTL:support . TTL 0v off ,5v on so supplying 5V to the TTL should trigger (turn ON) the laser The TTL is modulated by a PWM signal from controller to get various power output (longer pulse width --- more laser ON time) What firmware and software are you using? Many of SW programs allow selection of how laser is tby cozmicray - Laser Cutter Working Group
Why are you using this FYSETC great unknown board with Atmega2560 CPU (8 bit) and unknown firmware Klipper (not much of a user base to get help ) six drivers (but there is only ONE motor on Z-drive) ?? are you modifying Z to Three motor drive?? the FYSETC F6 V1.3 board detailed at: https://wiki.fysetc.com/F6_V1.3/ Klipper (Rasp-Pi part) will be running under OctoPrint in Rasp-Pi feedingby cozmicray - CoreXY Machines

"linear rails run in pairs are hard enough to keep perfectly parallel and true to each other adding a third would add another level of complexity which I'm not sure I would have the patience for." One linear rail would replace your dual rod guide .... so only three rails 2 rods parallel --- parallel to two other 2 rod assemblies ---- I see six vectors going every witch way --- ??

I've got a Vaeder V-struder feeding filament on DaVinci 1.0 The belt solution, which drives filament using belts. This allows for great torque on your filament, without slipping or damaging the filament. The geared solution gives enormous torque from even a simple stepper motor.by cozmicray - General
What is maximum current output of your 12V DC power supply? Your gonna need > 4 ampby cozmicray - Laser Cutter Working Group
The TTL trigger is not a voltage dependent control. The trigger pins normally are pulse width modulated (PWM) to control laser output More time ON ( at 5V) the greater the laser ON - more power. So you have to set up your control pin to PWM or select a pin that can set PWM frequency Readby cozmicray - Laser Cutter Working Group
