  1. does the Mark 2 conversion work with cura 4.1 I have it working on V3.2 was going to upgrade but want to check first..
  2. greatg no I have not connected it I have the mark two mod on so didn't see the point I thinking of getting UM3 and connecting it but not sure,, Ahoeben I agree that is a reason I'm not printing much with palette top picture is a product im developing so is a functional model (Proto type) it takes to long 18hrs in fact the purge block is the majority of the time the car was 10hrs but, im struggling with the waist,, there is however ways around the waist, my reason for putting the pics up is to show the Palette is an option and it does work...although I just stuffed my printer up using PVA which I wont do again...
  3. I am considering the kit to put on my Pallette and hook up my UM2
  4. trying to print a pyramid out, but its cut into 4. bottom piece and third piece printed by head 1 and the second and 4th piece printed by head two, how do you stop cura giving a bottom shell to the third piece while keeping the bottom of the first piece... help appreciated
  5. bummer im at the other end of country how much are you asking..
  6. yes interested how much can pick up depending where you are at
  7. Really like the look of this design which Firmware are you using is this custom,, also what slicer I use S3D and find the Mark 2 a little awkward to use with it... VERY Good work though highly impressive.
  8. Thanks for all the advise I tried the link and I thought you could alter the Kp Ki Kd values while you are printing ?? but I also hooked the Um2 to Pronteface and ran M303 E0 S210 C10 and this gave me Kp14.31 Ki 1.46 Kd 34.98 then added these values manually into the UM2 and saved this was better but at any temp change say from 215 to 210 it would drop to 202 and then climb to 210 I did the same procedure for the second head but altered the line to M303 E1 S210 C10 and in putted the results again manually... so I'm guessing the pid is not reacting quick enough to stop the drop in temp and recover to change??? the link you sent me suggest you can do this while printing ??? is that correct... if so how the menu is not available while printing??? again thanks for the advise...
  9. Tinkergnome Thank you for replying the oscillation has only raised its head since I installed the new Mark two, On the original head I am still ysing the original heater but I am using 3dsolex blocks,, I did suspect it was the Pid setup (sub-optimal) don't know this,, but I had done a Auto pid tune, but as I said the Temp is ramping up by 20 then back down although I don't know where 200c comes in when S3d has it set to 210,, (could be creeping)??. The link gives plenty of warnings but light on how to?? for the novice,,, I have Pronteface installed so might have a look on that,, Ill also print the link off and have a go at manually setting at the moment my settings for Head 1 are Kp 18.83 Ki 3.64 Kd 24.38 this was after a Auto Tune
  10. Does the Mark 2 Firmware handle the temp setting in a different way to when I just used Tinkergnomes Firmware for the STD Um2.. reason I'm asking I'm getting a lot of banding in the prints which I have never suffered with on the UM2,, my last print I noticed the temp reading on the display is going from 200 to 220 all the time during a print,, it climbs up then drops, continually. Im using S3D which I have always used before the Mark 2 mod and in my Temp Setting I have 215 for first layer them 210 ???????????? and yes I am using just the left head only (original head) the other is parked and NOT being used at all.. and is cold.
  11. gr5 thanks for the reply that has helped dropping the fan, but I seem to be getting the odd layer splitting in the print
