I have given up on making the changes in software and just switched around the stepper wiring on the Y and Z axes. Now everything works fine. For information I am using the SY42STH47-1684B1 steppers from Zapp Automtion and my wires go Red Blue Green Black on the X axis and extruder and (now) Black Green Blue Red on the Y and Z axis. RAMPS 1.4. Marlin firmware. Regards, David.by oddovalspin - RAMPS Electronics
Hi, Does anyone know how to change the direction of the axis in marlin? Both my Z and Y axes are moving away from the end stops when I click on the + buttons in Pronterface and Reprap host software and they move in the wrong direction when I try to home them. I know I can change the wiring but I would rather get this right in software. Thanks, David.by oddovalspin - RAMPS Electronics
Hi Everyone. I built a heated bed over the weekend. Basically I printed toner using Press 'n Peel and extched a track which has a resistance of about 2 Ohms. I also wired up a 100 kOhm thermister and hooked it up to T1 (T0 already has the extruder thermister. Today i hooked it all up and tested it with the Reprap host software and presto... I have moving axes. It might be worth noting to peopby oddovalspin - RAMPS Electronics
Andrew and Vollnormal, Thanks for your replies. I have the extruder thermistor connected to T0 but I don't have a heated bed. I have all the bits and will put it together this weekend and let you konw how I get on. Thanks again for taking the time to reply and for your advice..

Yes, I've used marlin and it compiles and uploads. I've changed the endstop settings to true for the H21L0Bs and set the board to RAMPS1.3 in pins.h It still compiles and uploads. I have posted another query about getting my board to talk to my laptop so i am waiting with baited breath. Thanks for taking the time to post a reply.by oddovalspin - RAMPS Electronics
Hi, I have RAMPS V1.4 hooked up to an Arduino Mega 1280. I can run the test code and the steppers all move, the extruder moves and the LEDS on the MOSFETS all blink. So far so good. I have downloaded marlin and sucessfully complied it. Marlin is basically the only firmware I could find which would compile and upload straight off the download so I figure that was a good start. I have read a nby oddovalspin - RAMPS Electronics
Hi, I found this test code very helpful. When I load it onto my board and power it up, the 3 stepper motors run one way and then then other and the extruder runs one way and then the other. The LEDs around the heater outputs pulse so I figure my board and wiring is all OK. But I can't get my board to connect work with any g-code generators. It would be really useful if the test code was able tby oddovalspin - RAMPS Electronics
