Interesting thread to read through. Do any of you who are converting machines have any left-over MakerBot electronics - dead or alive (or in between!) that you might be willing to donate to a project I'm running to create a drop-in Mightyboard replacement for the Rep2/2X? I've just successfully restored several machines, but one was completely missing its motherboard and would be a good candidaby alexgibson3d - General
I found that a fix posted in the Repetier forum also works in Marlin I was compiling Marlin 1.1.x on Arduino 1.8.2 for RAMBo 1.2d I got this error: 'DIGIPOT_MOTOR_CURRENT' was not declared in this scope I uncommented the line below in Marlin's Configuration_adv.h #define DIGIPOT_MOTOR_CURRENT { 135,135,135,135,135 } // Values 0-255 (RAMBO 135 = ~0.75A, 185 = ~1A) ...and it compiles fine.by alexgibson3d - Firmware - Marlin

Did you find an answer to this? I am there right now! Cheers Alexby alexgibson3d - Firmware - Marlin
+1 for edgeconsults solution With one caveat - While 99.9% of USB cables have internal wires coloured Black, white, green, red, and there is a colour coding standard where Red = 5V... DON'T ASSUME that this colour code has been respected inside a random sealed-plug USB cable from Far, Far Away... I spent a frustrating time debugging an implementation, where the USB cable had 5v=black!!! The Uby alexgibson3d - General Mendel Topics
Hi all I have a 90mb STL slicing right now. It has been since yesterday, nearly 24 hours ago.

Test 4: 1) Homed x, then y. 2) z +20 3) Motors Off 4) Manually pushed X carriage to about Y -100, X +100 5) Home all - behaved correctly X-Y-Z Repeated steps 2-5 4 times - all perfectly.by alexgibson3d - General
Test 1: 1) Homed x, then y. 2) Sent Y -100, X +100 3) Motors Off 4) Home all - behaved correctly X-Y-Z Repeated steps 2-4 4 times - all perfectly. Test 2: 1) Homed x, then y. 2) Sent Y -200, X +200 3) Motors Off 4) Home all - behaved correctly X-Y-Z Repeated steps 2-4 4 times - all perfectly.

Replaced both RAMPS and Arduino Mega. Same issue still occuring. It seems to be intermittent, and may depend upon where I have pushed the carriage to before homing... Test Method: 1) Home X-Y-Z via Pronterface 2) Note behaviour A 3) Motors off 4) Push carriage to rough middle of build bed 5) Home X-Y-Z via Pronterface 6) Note behaviour Bby alexgibson3d - General
Photo attached as requested. Will replace both the RAMPS and Arduino Mega with new ones as my second shot this evening - the first will be to re-seat every connector in case that was the reason...by alexgibson3d - General
Small additional piece of information - on the printer that is misbehaving, if I have already homed X, but not Y or Z, I get a different behaviour: X backs off 5mm, then returns to home (min endstop), then Y homes to max endstop as it should! Then Z homes correctly. So the incorrect behaviour is narrowed down to on one of 2 identical machines, if X is not already homed, G28 will home X, skip Yby alexgibson3d - General
Hi all I would appreciate some ideas to troubleshoot a weird issue. I have built multiple 3D printers of different types and this is my own design of CoreXY, of which I have built several examples, so I am surprised to be having this issue, and it's either going to be something ridiculously simple I forgot, or something tricky to troubleshoot. I need to try to fix this by Monday...! Environmeby alexgibson3d - General
Hi, I encountered the same heater error issue upgrading 'Morerod', my extended axes RS red Ormerod 1, to 1.09. I followed Ian's step 3) which has fixed this issue, but I now cannot get the z probing to work, the values fluctuate wildly. At the same time as upgrade the firmware I also (at last) added the RRP modulated z sensor. I got that working seemingly well last night, before applying fixby alexgibson3d - Ormerod
Hi, late response here, but I am very interested in your approach to make the lxpresso compatible with ramps-fd, which I have, and was looking to do myself. Do you still have spare boards or the design files so I could recreate your work please?by alexgibson3d - Controllers
Hi there, did you get or find an answer to this please? I am running into similar issues...!by alexgibson3d - Firmware - mainstream and related support
Hi Vincent I am going to get some of your really nice board made. Do you already have plenty or would you like me to send you a few to say thanks? Are you happy for me to put them on eBay in the UK to enable other local RepRappers to jazz up their machines? I am working to develop some software to enable RAMPS to control over I2C another Arduino running code to drive Adafruit Neopixel styleby alexgibson3d - Developers
Hi, thanks Salsabettis I found this extremely helpful.by alexgibson3d - General
Hi Henrik and Chris, Massive thanks for posting your solutions - same issue here, 680ohm resistor pins 2-3 sorts it totally. I went for a surface mount between the pins, for reliability and to look less hacked. Superb. Cheers, Alexby alexgibson3d - RAMPS Electronics
