Re: Going soluble - printing PVA
So how does it look after dissolving the PVA? How long did it take to dissolve?

Re: Help!!!! Dual extruder problem
I'm using the wiring harness that came with the M@, I haven't upgraded anything. Josh - Any more thoughts about the harness? brettb and I are both using that old style harness. Because of the second extruder the signals travelling back and forth through the harness have changed quite a bit. The fac...

Re: Help!!!! Dual extruder problem
I've changed the E1_MS2 pin definition as you suggested and the thermistors read properly at the default 16x microstepping. But now neither extruder will work - I'd expect that for the second extruder but not the first. There was also some other weird behavior such as occasional erratic control of X...

Re: Help!!!! Dual extruder problem
That shows that x1 and x2 microstepping are the only modes with MS2 LOW; since one of the changes that has occurred here is using the E1 stepper motor driver for the first time, it may be that the E1 driver's MS2 pin is behaving strangely (I actually noted in the "M350" echoes from before, that the...

Re: Help!!!! Dual extruder problem
What version of the Arduino IDE are you two using? And what, if any, extra libraries do you have? I've been using Arduino IDE v1.0.5 but I also tried v1.0.4 but it made no difference. Not using any extra libraries. I've tried debugging further but with no success. The lack of debugging tools and th...

Re: Help!!!! Dual extruder problem
OK, a little more testing shows that, using the unmodified dual code, you can issue "M350 S1" which sets microstepping to 1 and all the thermistors read properly. "M350 S2" also works. But any microstepping higher than 2 causes reading the thermistors to fail.

Re: Help!!!! Dual extruder problem
One possibly useful test - could either of you try using the same firmware as a single, with "#define EXTRUDERS" set to 1 in Configuration.h (line 65)? I can confirm, as Brett did, that changing EXTRUDERS to 1 did not change the behavior. I also confirmed that I am running with a v1.2g Rambo board.

Re: Help!!!! Dual extruder problem
Q*bert and brett - what specific RAMBo revisions do you two have? And did you change the firmware at all before uploading (the steps/mm for instance)? And/or, have you changed anything in EEPROM on your old firmware? I upgraded my Rambo to v1.2g (if I remember right - I'll check tonight.) I didn't ...

Re: Help!!!! Dual extruder problem
I'd reported the exact same issue http://forum.makergear.com/viewtopic.php?f=13&t=755&start=90#p4452. It looks like we've both done the same trouble shooting, let me know if you resolve the issue. After a few hours of debugging, I found that the problem is related to how 1/16th microstepping is ena...

Re: Help!!!! Dual extruder problem
Thanks Rick - will do.
Very impressed with the quality of the upgrade components!
