Sorry to take so long to get back to you guys. No school over the weekend so we just got back to it today. To answer your questions: We tried reflashing the firmware today - It didn't seem to change anything We have not tried Printing anything because we are still commissioning the printer, however we talked it over today and decided to go ahead and finish the commissioning and try printing.

I tried sending the M83 command before the G1 command as you suggested and here are the results M302 M83 G1 E5 F500 (Extruder didnt turn) G1 E12 F500 (Extruder ran forward) G1 E-5 F500 (Extruder ran reverse) NOTE"E" NEGITIVE VALUE G1 E-8 F500 (Extruder ran reverse) NOTE"E" NEGITIVE VALUE G1 E-6 F500 (Extruder ran reverse) NOTE"E" NEGITIVE VALUE G1 E3 F500by ricym66721 - General
Here's an update. Using Pronterface (Printrun 2014.03.10.) When we use the graphical button for extrude, and set the length(amount) to 5mm and the speed to 500 mm/min then it works fine on both "Extrude" and "Reverse" buttons. But - when we send a "G1 E5 F500" it does nothing ---------when we send a "G1 E0 F500" it does nothing ------when we send a "G1 E15 F500" it works fine ------when we sendby ricym66721 - General
Thanks for the input, 3dkarms Already tried that, We tried slowing the feed rate down to as low as 100, and speeding up to as fast as 900 , and everything inbetween. It didn't do anything. The extruder doesn't even make a noise. The only thing that works is making the "E" value 10 or greater. Then the extruder seems to work fine.by ricym66721 - General
Sorry for the confusion, I should have proof read my post better We changed the 'E" the line that read: When we calculated our M92 we got 633.6 , so we changed "M92 Z636.6" but that didn't help. should have read: When we calculated our M92 we got 633.6 , so we changed "M92 E636.6" but that didn't help. and the line that read:by ricym66721 - General
At school we are building a reprap mono. We are using Melzi electronics. A couple of days ago we had a problem with microstepping and you guys solved it right away. We now have all the motors microstepping at 1/16 step. X , Y , and Z motors are moving the correct distance. _ THANK YOU The problem we are having is with the extruder motor. The commissioning instructions say to send a "M302"by ricym66721 - General
THANK YOU nophead , waitaki , and DaveX That was exactly what we needed. We soldered the three jumpers for each motor driver , and the X,Y,Z, and E steppers are moving as they should. We have set the endstops and homed the machine. In the next few days we will finish the commissioning. Thank you again, YOU GUYS ARE GREATby ricym66721 - General
Thank you for your quick reply I am not sure if I am checking this correctly, so I attached a picture to help clarify.(Please see MS1b.jpg) When I check across the two pads of MS1 I get a reading of 5 volts When I check across the two pads of MS2 I get a reading of 5 volts When I check across the two pads of MS3 I get a reading of 5 volts I hope I am doing this correctly, please let me know ifby ricym66721 - General
At school we are building a reprap mono with a melzi controller and are having a problem with the melzi. All of the stepper motors are moving a full step instead of 1/16 step. It was my understanding that the melzi controller would move the steppers 1/16 step automaticaly and there is no jumper or setting on the board for this. I have researched this on the internet and not been able to find anby ricym66721 - General
