  1. Well I still haven't rolled back. The work-around supplied by Simplify3D seems to be working, just staging the heating so everything doesn't draw power at the same time.

    Regarding the header, it is not missing. I only pasted here the snippet that S3D calls startup. The full gcode has a header, but some commands are missing, particularly the EXTRUDER_TRAIN... commands. It is pasted here.

    ;START_OF_HEADER

    ;HEADER_VERSION:0.1

    ;TARGET_MACHINE.NAME:Ultimaker 3

    ;GENERATOR.NAME:Simplify3D

    ;GENERATOR.VERSION:3.1.0

    ;GENERATOR.BUILD_DATE:2016-10-03

    ;FLAVOR:Griffin

    ;BUILD_PLATE.INITIAL_TEMPERATURE:60

    ;PRINT.TIME:11836

    ;PRINT.SIZE.MIN.X:0

    ;PRINT.SIZE.MIN.Y:0

    ;PRINT.SIZE.MIN.Z:0

    ;PRINT.SIZE.MAX.X:215

    ;PRINT.SIZE.MAX.Y:215

    ;PRINT.SIZE.MAX.Z:200

    ;END_OF_HEADER

  2. The folks at Simplify3D have also been working on this problem and have send the following startup gcode for me to try. See copied response to their email below.

    My response:

    Thank you very much. It came at a convenient time so I tried it right away. It worked from a completely cold start. I must say, however, that recently other files created by Simplify3D have also worked. If I understand the gcode correctly, what you did makes sense, you are heating one element at a time and waiting for it to reach temperature before turning on another. Makes sense, but I can’t guarantee that it’s solved the problem and it won’t come back.

    Nor do I understand the interaction with the new firmware, unless Ultimaker is trying to heat to setpoint faster than it used to.

    Simplfy3D's Email:

    The combined heating could very well be the issue with these prints. Can you please try adjusting the start script and recreating the file? I've adjusted the start script and included it below.

    M106 S0 ; fan off

    M204 S1500 ; default acceleration

    M205 X15.00 ; maximum X Y jerk

    T1

    G1 X20 Y5 Z5 F15000.0 ; heating location

    M140 S[bed0_temperature]

    M190 S[bed0_temperature]

    M104 S[extruder0_temperature] T0 ; heat left

    M109 S[extruder0_temperature] T0 ; stabilize left

    M104 S[extruder1_temperature] T1 ; heat right

    M109 S[extruder1_temperature] T1 ; stabilize right

    G1 Z0.2

    G92 E0 ; zero extruder

    G1 E30

    G92 E0 ; zero extruder

    G1 X120 E15 F1000 ; purge right extruder

    G92 E0 ; zero extruder

    G1 E-12 F900 ; retract prior to tool change

    G92 E0 ; zero extruder

    T0

    G1 Y5.5 F15000.0 ; allow space for left purge

    G92 E0 ; zero extruder

    G1 E30

    G92 E0 ; zero extruder

    G1 X2 E15 F1000 ; purge left extruder

    Please let me know how well this works for you when starting from an environment where none of the heaters were heated up previously.

  3. Well now I don't know what to think. I tried a new Simplify3D file today, expecting a reboot and I was watching the LED on the power "brick" -- sorry, new term for me and I didn't know what you were referring to -- to see if it went out. Lo and behold, the print started without rebooting.

    Now I don't know if this is random or what. Since upgrading firmware, all S3D files rebooted, and then sometimes restarted. None of the Ultimaker files did. But some of that could be that by the time I tried the Ultimaker files, the heaters were already warmed up.

    Or could it be something in my file. I regenerated my stl's and tweaked some of the settings in S3D, so maybe it's something there. I'll send a message with my latest file that printed today.

    Additionally, I contacted Simplfy3D about the issue. They said they hadn't seen this problem "in some time." So, they've seen it before? I'm going to send them some files and see what they have to offer.

    I do prefer Simplify3D over Cura, primarily due to it's handling of support. And it is a common interface for our multiple printers.

  4. Just had another reboot, with a file created on Simplify3D. The blue light around the wheel on the front went out, if that is what you are refering to. I dumped the logs to the usb. They are here:

    Ultimaker Logs

    Password: VkihEQqA

    https://campbellu.egnyte.com/fl/cHi2I7uVCC

    The next file, created in Cura started fine.

    Regarding the heating hypothesis, the extruders were already warm, since I primed them first. So I really don't know how relevant that is.

  5. What you say makes a certain sense, however,

    - why would it just appear after the firmware upgrade? Does the new firmware perhaps heat more quickly?

    - why would why would it matter if it the gcode were created by Cura or Simplify3D? Or is that just random? Since the firmware upgrade all my files created on Simplyfy3D had the reboot, and the only one I've tried from Cura worked.

    I don't know what LED you want me to check. Yes, they are the original Ultimaker print cores.

  6. I have fixed the unrelated problem with Cura by rolling back intel graphics drivers https://ultimaker.com/en/community/51884-cura-doesnt-respond?page=1&sort=#reply-192500

    I have finally been able to create model with cura to send to the ultimaker. It started printing fine without rebooting, so the issue seems to be with gcode generated by Simplify3D. Sorry I forgot to get a log file before printing. I'll try to get one later.

    I hope I can go back to Simplify3D as I prefer it's handling of support structure, in particular it's ability to manually manipulate support. I will contact Simplify3D to see what they say about this issue.

  7. I've mostly been using Simplify3D, but for troubleshooting purposes, I've been trying to do some things in Cura. I'm on Cura 3.04, which I believe is the current version. Most of the time when I click, it does nothing. It just sits there. I click and click and eventually it does something. What's up with that?

    I'm on Windows 10. It's not an OS "This program has stopped responding." It just doesn't do anything.

  8. Three times today my Ultimaker 3 Extend has rebooted at the start of a print. It goes through the initial checks and heat up, is about to start, and then it reboots. I resend the same file, and it works.

    I just updated firmware to 4.0 Is that part of it?

  9. We were using some crappy esun filament that was 3 mm. Now everything is 2.85, from ultimaker, matter hackers, and a local company who sent us some free samples. Same results.

    I don't think we are in a particularly dusty environment.

    I have wondered about print speeds, or rather, what if the gear speed doesn't match the print speed? This is just speculation on my part, I have no evidence that this is occurring, but what if the gear is turning faster than the filament extrudes? Might filament back up and the gear start to grind? Then, might ground distorted filament cause problems when it reaches the extruder?

  10. Yes, PLA is clogging. We gave up entirely on PVA because it it's clogging and environmental needs. Might get back to it, but not until PLA can be reliable.

    PLA seems to stop extruding and the gear grinds the filament. It is almost always a clog that is easily cleared. But why should it happen so much? Happens with different brands.

  11. My Ultimaker 3 clogs frequently. I see a lot of discussion about how to clear clogs, but little on why it clogs so much. I mostly use PLA with default settings. The clogs are easy to clear, but we lose many prints and waste a lot of time.

    Why does it clog so much? Is there something that can be done to lessen the likelihood of clogs?
