Printing multiple colors with single extruder

[Matt_Sharkey]

hmm I dont foresee that i will be using a VIki anytime soon. Is it possible to use the M600 command with pronterface? after appropriate firmware updates of course

Yeah, it's just more awkward. you might be able to send it during the print.

Downloaded and installed the LiquidTWI2 and Marlin.ino compiled OK. Uploaded it to my M2 and lost communications via USB and the Viki mostly quit working. Built my old code using the new LiquidTWI2, uploaded it to the M2 and all is again OK but with old code. Since my old code built and runs OK with the new LiquidTWI2 , that set of files must be OK. Something in the new code is incompatible with my machine, M2 24V single V3B aned VIKI.

The firmware I'm using sets the baudrate at 250000, which is a frequency Linux hosts can have problems with. It's at the top of Configuration.h

As for the Viki, what problems was it having?

[femyers01]

I set the baud rate to 115200 in config.h and uploaded. For some reason I got lots of timeout errors on the upload. Tried it a couple of times and keppt getting timeout errors. Finally tried the M2 and it seemed to run OK but acted like it had the old code in it. I need to regroup and figure out where I am.

The trouble I was having with the viki when I had the baud rate set wrong was that nothing seemed to work except the center button and the position on the right side of the circular control. Nothing else did anything. The display looked the same as the old code.

Got the new code uploaded with the baud rate of 115200. Started a print from the SD using pronterface. As the print was running I noticed it was only printing the upper right quadrant of a circle, not the whole thing. (I was printing a bracelet but got a quarter of a pie instead) Anyway, I tried the M600 X205 Y100 Z100 E-10 L-80 and it seemed to work. However when I continued after that, the machine went about 50 X unites toward X0 and started printing in another place.

Meanwhile, the Viki still doesn't work hardly at all with the new code.

I'm going back to my original M2 Viki code for a while.

Wow, how is that code so broken? That's literally a copy+paste of the firmware I use on my 24v M2.
