  1. Just to say thank you to Tinkergnome who answered all my questions, its taken me along time to get to this point Not the best print I have ever done but then again, I don't use cura so not bad the PVA came out well though. see it in action https://www.dropbox.com/s/xm8tcyb83rwqj32/2hd%20Ultimaker.MP4?dl=0
  2. Thank you for your input I'll carry on learning the Cura, will print with PVA tomorrow. Thanks again.
  3. Tinkergnome as always thank you for your reply, can I ask the firmware version I'm running is 17.09. I checked your GitHub Mark2 Page and you have version 19.03 is it worth upgrading to this, and if I do would I have to recalibrate the Mk2,, also I have a menu option of Prime / Wipe position and it was set at X 105.00 Y27.00 which I changed as a test to X111.00 Y87.00 which might of helped, or am I just kidding myself?? but do I need this option??
  4. I'm having a problem in that for some reason when the head changes to second head on first layer, it goes across the print then goes to prime tower, I checked the Gcode in S3D and there is no Movement to this point, I also checked it in cura and it does not show this move, is there anything in the Firmware that specifies a move like this, after the first layers everything is fine, I show the first layer and marked in red is where the head goes from picking up. Any advise welcome Im stumped..
  5. Just found this thread I was told Cura was the best for Dual material printing until I used version 4-4 and found this problem what a pitty they decided on this route.
  6. Forgot to ask I see a lot of this "This setting has been hidden by the active machine and will not be visible" while Im trying to activate some options
  7. Tinkergnome, thanks for the reply, I think that's ridiculous bring the left head for a 4 second print every two layers who on earth thought that was good, unbelievably bad, I looked at my cura (4-4) setting's and cant find Compact, I only have 7 setting for prime tower 1 enable prime tower 2 prime tower size 3 Prime tower Min Volume 4 Prime tower X position 5 Prime Tower Y Position 6 Wipe Inactive Nozzle on Prime Tower 7 Prime Tower Brim I tried 6 on and off made no difference I now understand why,, Below is a picture of my print , I will experiment with the position of the model / Prime tower tomorrow I moved it to the right for some reason the head was ploughing of my print to change head / prime tower/// any more advise welcome..
  8. hears a picture if you look at the prime tower its only red while printing Red Material sections, but when its printing the Green sections the prime tower is red and green how do I stop this..where have I gone wrong...
  9. hope some one can help me hear, got my Mark 2 printing with cura 4-4 don't know what I have done hear but, when printing dual head it will print with head 1 and go to prime tower do a layer then back to the main print ect, BUT when the second head comes into play it will print 2 layers, then change heads (hd1) go to prime tower do 1 circuit on prime tower then change to (hd2) and will carry on how do I stop it from just changing head do a prime tower print then swap back>>> my first print is looking quiet ugly heavy retraction marks ect on the outer surface,, and advise welcome...
  10. tinkergnome thanks for the reply, I think I was thrown a little by the little information on screen, I seem to remember possibly nozzle diameters, but I am probably wrong, I know the nozzle size is in advanced and found that setting in latest cura,, as I said many times I have not used cura or my UM2 for a long time and just trying to setup now in latest software, thanks for the advise I think it wont be the last time I ask, as setting up my Mark 2 I find difficult..
  11. I had a mishap with my hard drive so had to install Cura so decided to go for the latest, it took a few attempts for cura to slice a model for the Mark 2 I think the heads were disabled (?) any ways I got cura to slice but when I look at the printer under preferences machine setting there is a start script for the printer and end script but when I select extruder 1 or 2 there are no scripts just material ,diameter (2.85) nozzle offset X 0.0 Y 0.0 cooling fan number,, no nozzle sizes nothing is this correct, sorry for the vagueness but did use the UM2 much lately but now need it.. any advise welcome
  12. cloakfiend I understand, when I first started out with 3d printing I was learning by myself (made loads of mistakes and learned from them) didn't seem to get away with cura, and at the time S3D was in a field of its own, if you were planning to use Multy extrusions it was the thing to learn ,, how time's have changed🙄
  13. RudydG thanks for the advise have not placed order YET still thinking, I take on board and totally agree about S3D I use it all the time but can see an end to it with the UM3S Thanks for the advise.
  14. Just Returned from the TCT Birmingham and I'm seriously considering buying the s3 I like the footprint I like what I see under the bonnet, but I'm after reliability and quality of print, along with reliable Pva Supports, I've made no hiding the fact I don't use cura but will have to get over that, I would of like however the s5 material handler to be usable with the s3, if I have to watch moisture with pva it does not make sense to me to have to find a third party product that will do the job.. I think UM are moving away from the makers which is a bit sad but I think UM should also be aware with such a high price tag comes commitment from UM that the product is working and working well, if not then this erodes there Kudos. I think my s3 is in order ??
  15. chputney thank you for your advise I use notepad ++ and I place the pause where I want it, I will try the G1 instead of the G92 thank you for your input..
