Hi Bill! Is there a process to reset the micro-controller on the 3D Chameleon control board? I almost had my configuration tuned, when it started malfunctioning. When I start the print job, it resets (7 pulses) fine and selects T0 (1 pulse), but when it feeds T0, it only goes 2/3rds of the way and stops. I thought I'd changed something in the G-Code to cause this, but nothing in that portion of the code has stopped. What's really wierd is that the next press of the switch starts feeding T3! Susequent presses feed or extracts other lines. It takes multiple presses before it starts pulsing again. I tried unplugging and replugging the control board, but it repeats the same problem. I currently have it unplugged to cool awhile.

I know this isn't completely 3D Chameleon, but it is necessary to get mine working. I'm trying to write the gcode to use my 3D UnderClippy, referencing the profile included with the 3DClippy. The part of the code that just won't work is as follows: G0 X235; move to cut position G91; set to relative mode M92 X8 ; Set X steps to 1/10th (high torque) G92 X0 ; Set X to 0 ; cut off filament tip G0 X300 F10000 ; Cut the filament quickly G0 X-300 F10000 ; Move X back to position G90; back to absolute mode ; set X back to normal M92 X80 ; Restore X steps G92 X235 ; Restore X position Now, my problem is that any movement of X after this cannot be moved below 230. M211 reports: Min: X235.00 Y-30.00 Z0.00 Max: X495.00 Y240.00 Z230.00 How do I set X's minimum back to 0? Thanks, Tony

I'm still struggling to get my 3D Chameleon to operate properly. Yesterday, I decided to start over configuring PrusaSlicer, closely following the Chris's Basement video 3D Chameleon - Part 3 - Your First Print. In it, he instructed me to create a script to measure the feed speed of the 3D Chameleon. His results were 34.5mm per second. My results, on the other hand came out to only 17mm per second! Is there a method to improve the speed of the 3D Chameleon feed? Thanks!

I've successfully connected the 3D Chameleon control board to the Power Control port of my BTT E3 Mini V3. It's connected to pin PC13, translated to pin 45 in g-code. The commands that work and have been tested are: M42 P45 I1 T1 S1 ; Initialize 3D Chameleon (off) M42 P45 S0 ;Activate Command Mode M42 P45 S1 ;Deactivate Command Mode Now I tried writing a short G-Code script to set the pulse time to 100ms. The above commands work, but when I execute the G-Code below, the control board just pulses every half second until I manually issue the M42 P45 S1 command. Is this command no longer supported or am I doing something wrong? M42 P45I1T1S0 ;Initialize Pin and set G4 P7500 ;Pause for 15 pulses M42 P45S1 ;Release Pin G4 S3 ;Wait 3 seconds M42 P45S0 ;Set Pin for delay G4 P100 ;100ms M42 P45S1 ;Release Pin G4 S3 ;Wait 3 seconds M42 P45S0 ;Set Pin for delay*2 G4 P200 ;200ms M42 P45S1 ;Release Pin Thanks!

This has been so frustrating! I've been trying to do my first multicolor print job, using the 4 square example I found somewhere here. It worked great for the first two colors, but failed to produce 3 pulses to choose T2, instead producing 4 pulses to choose T3. I finally created a GCode test file to test the half second delay: ; ******************************************* ; This is to test the 3D Chameleon switch timing ; ******************************************* ;; Reset feed rate and flow rate. G90 ; Set all axes to absolute M220 S100 ;Set Feedrate ;M221 S100 ;Set Flow Rate G28 ; home all axis G0 Y235 F2000 ; Switch Triggers @ Y238 M117 Testing G4 P10000 ; wait 10 seconds G91 ; move to relative mode ; press the button G0 Y3 F2000 ;Test Reset Command G4 P3500 ; 3.5 seconds to trigger Reset ; release the button G0 Y-3 M117 Reset Test Complete This should produce 7 Pulses to reset the Chameleon. Instead, it produces 8 pulses! I experimented with the delay and arived at (450ms * 7) to get the 7 pulses. I then wrote this code to try setting the delay: ; ******************************************* ; This is to test the 3D Chameleon switch timing and set it to 1/2 second. ; ******************************************* ;; Reset feed rate and flow rate. G90 ; Set all axes to absolute M220 S100 ;Set Feedrate ;M221 S100 ;Set Flow Rate G28 ; home all axis G0 Y235 F2000 ; Switch Triggers @ Y238 M117 Testing G4 P5000 ; wait 10 seconds G91 ; move to relative mode ; press the button G0 Y3 F2000 ;Test Reset Command ; 3500 give 8 pulses. Changed to 450 per half sec. G4 P3150 ; 3.5 seconds to trigger Reset ; release the button G0 Y-3 M117 Reset Test Complete G4 S5 M117 Press for 15 pulses G90 G0 Y150 F2000 ; Move out of the way to press manually G4 S10 ; Wait 10 seconds for command to be entered G0 Y235 F2000 ; Position for triggering again G4 S2 G91 G0 Y3 F2000 G4 P500 ; Press for 1/2 second G0 Y-3 F2000 G4 S5 ; Wait 5 seconds G0 Y3 F2000 G4 P1000 ; Press for 1 second G0 Y-3 F2000 M117 Test again Unfortunately, this results in about 1/4 second pulses. I'm at a loss...

I'm having a hard time figuring out where to mount the trigger switch on my highly customized Ender 3. I've figured out how to control it with an I/O line on control board, but if like to also have the option of the mechanical switch got manually controlling it. If it feasible to connect the switch on parallel with the GPIO control?

I just watched a video on YouTube where you demonstrated a new version of the 3D Chameleon (Mk4?). Will this be the version I'll be purchasing? Thanks!
