Welcome to the SeeMeCNC Community

Couple of questions. First one is, what manual code should I issue from RepetierHost to turn "dry run" off? I don't see anything referring to "dry run" in the Repetier.ino list of implemented gcodes (for example: https://github.com/seemecnc/Repetier-09 ... petier.ino )

Second, what is "ditto mode?" From the .ino: "- M280 S<mode> - Set ditto printing mode. mode: 0 = off, 1 = on"

I'm running RAMBo 1.1, firmware is .91 Rostock as modified by SeeMeCNC.

Appreciate any thoughts, thanks in advance...

In marlin firmware M302 "allows cold extrudes"
I don't know if that is what you are looking for or if it will even work with Repetier fw

I use the button in Repetier labeled [Dry Run] to do testing when I don't want to actually print.

It doesn't appear to be documented, the easy way to determine is in Repetier host, to turn on the echo to console settings and push the button in the UI.

Thanks guys, I appreciate the quick replies.

polygonhell: rephost sends M111 S15 to turn dry run on, and M111 S7 to turn it back off.

I'm asking if there is documentation somewhere in repetier because my extruder stepper is disabled and M111 S7 does not turn it on.

A little more background:

I am asking because I am wondering if there is some other setting needed to re-enable an extruder when dry run mode is set to "on" after a thermistor fail. I had that happen a couple weeks ago, I've rebuilt the hotend and got the new thermistor installed (and thanks to earlier help from polygonhell, I've got the thermistor table adjusted accordingly as well), but it won't via control from the manual panel. I've turned it all on and off several times, pulled the power plug out, hit the soft reset button, etc.

I know it's not the stepper or the wiring, because if I put the stepper wires on the free Z-axis pinouts, the stepper moves when I jog Z. I just can't jog the stepper from rephost. When I try, it doesn't even power the stepper- I can turn the gears freely with my hand.

I also know it's not the extruder 0 driver or pins because I went into pins.h and assigned extruder 0 to the pins for extruder 1 and then switched the cable to the free extruder driver. Again, no dice.

So at this point I'm wondering if there is something that I'm missing in the software.

Is there a list somewhere of what M111 can set/unset? I'm not seeing it in the firmware documentation.

oh, and "ditto mode" is a setting to extrude from two extruders, simultaneously. So you get two copies instead of one (as long as the parts don't overlap). Not relevant here.

M111 just sets the debug level, it looks like he sets bit 3 to enable dry run, and turns it off to disable.
You may be able to query it with M111 with no argument, if not your kind of stuck not knowing what else you are turning off.

OK, I'm at the office today but I'll try a couple of things when I get home.

So, it turns out, I was trying to fix a problem with the printer but the "real" problem was on the keyboard end of the USB cable.

Or, phrased differently, I think I was forgetting to run the "clear EEPROM" sketch before uploading the new .91 firmware.

Because i tried all kinds of stuff to fix this problem (see below) and none of it worked. So I was like "dammit. I am going to revert to the last-good .91 firmware I had, before I started messing with this thermistor issue."

So I did, and that didn't work either. So I went back to the upgrade instruction thread, and... voila, there at the beginning of .91, Jon says- you should clear your eeprom before you upload .91.

So I did THAT. And then I uploaded .91 with my new beta value for this new thermistor (it worked out to be about 4100 to get accurate at 200C, instead of the 3750 on the datasheet), and uploaded my old EEPROM settings, and now everything is just ducky again.

So I feel pretty stupid, because the step I was missing was "follow the damn directions."

Here's some M codes I learned in the meantime, no idea if all of these apply or not.
