Thank you for sharing the firmware. Good job on the hard work.
Todd,
Do you happen to have a picture or a diagram of where and what orientation you have the servo plugged into for the firmware file you sent?
Thanks,
Chadd
The reason I ask is that earlier in the thread it looks like you set the servo up on PWM1 but unless you split apart the servo connector you are probably using pins 1, 3 and 5 on EXP 3 for your servo. That would be running the servo off of 12V. Not sure what servo you are using but my servo is 5V so it would need to run off of pins 2, 4 and 6 and use PWM2. Pin 2 is 5v
Anyone else have input on the servo connections?
Ok here is what I did on the servo. I hooked mine up so that it would operate off the 5V line so I am using pins 2 (+5V), 5 (gnd) and 6 (pwm2).
To do this I modified your FW with the following.
#ifdef NUM_SERVOS
#define SERVO0_PIN 5
#if NUM_SERVOS > 1
#define SERVO1_PIN 4
#endif
//if NUM_SERVOS > 2
// #define SERVO2_PIN 5
//#endif
//#if NUM_SERVOS > 3
// #define SERVO3_PIN 4
//#endif
#endif
you said my name i don't have rumba :-) but i dont think you were talking to me
I am using pins 6, 4 and 2 on the EXP3 port. They are PWM2, Ground, and 5volt respectively.
If you use the firmware I posted and these pins you should be fine as it is working for me. I think i mentioned somewhere that I had intended to use PWM1 but it was later posted that PWM2 can be used. I have that pin defined in my firmware and my abl is working as it should.
I just can't get this thing calibrated to print even close to what I want it to print at. None of the parts are usable as they do not align well at all to the drawings. Everything is slightly too large.
If you have the option in your slicer have it do perimeters first then move in. That will help combat the sizes being overlarge
