  1. Thanks Enigma, we did not know that!
  2. We had an incident not long after we bought our 5S that the print head crashed and pushed the glass free of the clamps and scratched the aluminum platter below. It happened on the weekend during a long print. When we left the factory on Friday, it was operating completely normal. We think it was due to a power spike/fluctation surge as our facility is in a rural area. The hot end actually came in contact with the aluminum under the glass and put a scratch into it. In order to do this it pushed the 3D print to the side and overcame the resistance of the bed clamps. On Monday we found the glass pushed to the side. Call it impossible, but it happened. Since that time our right/left belt is loose. It must have tried to self-correctedsomehow because it proceeded to print the rest of the 3D print as a birds nest of material. A major design flaw of the 5S is the inabiltiy to adjust belt tension on the main belts (you can adjust belt tension from the drive motor to axis, but that is only 1/2 the tension required. Ultimaker should take note of the cheap consumer printers like Creality where you can adjust belt tension easily. We like the Ultimaker overall but just pointing out something to improve in the future.
  3. To answer the question about the sensor. Yes, the ultimaker brand materials have a rf chip in the paper of the spool and the sensor to read it is in the spool and there is a plug that connects it to the mothership. Regarding the crumbs in the tube from PKlemm. Agree- first thing we try after the message. we've had that issue and it works to blean out the bowden tube. The issue we were originally having is we bought a 5kg spool of PLA and the traction motor is not rated to turn a spool of that mass. We verified that with Ultimaker technical support. It might work for you, but touch and go. Also we had some poorly wound spools where the material was binding and it couldn't pull out the snag. REQUEST TO ULTIMAKER: Please, if you can, include the specific spool# of this error in your error message in your next firmware update(if it can interface w/hardware that way).
  4. I struggled with this for hours today and discovered i had the skirt turned on which was overlapping in the "preview" but didn't show up in the "prepare". Once i turned the skirt off (I would think same thing would happen with brim) I placed the parts within a millimeter of one another and the edge. Another thing you can try is lock model under the move commmand. You cant drag it with the arrows, but you can type new values to force it wherever you want. It still allows you to rotate the part also dynamically with the wheels. Another thing i found is if the file is saved exactly like it is in the picture, and reopened all the models "explode" and are pushed apart. This maybe due to the fact that under Preferences-->Configure Cura(Ensure Models Are Kept Apart) was checked on. Am scared to try it because i have to print many sets of these and don't want to redo the placement.
  5. In regards to CarloK post: In regards to CarloK's post: I found this post very helpful. In looking at the pressure settings, i found that one indicator was all the way up. Reason: the head of adjusting screw was on top of the feeder instead of inside. In other words, if you can see the head of the tension adjusting screw on top of the material feeder, then it needs to be pushed back inside body of the feeder. To do so turn the screw into the thread all the way so your not fighting the spring. Then put the cover on and back it out to the setting CarloK recommended in middle. The only thing you should see from the top of the material feeder is a 2-3MM hole through the white plastic. Then you insert the Ultimaker supplied tool into it fits into the screw. The head of the screw is internal pushes up against the inside of the body. While removing the cover from the material feeder, the screw must have popped out through the hole, therefore, it was not supplying any tension to the spring. So if you take the cover off the back of the material holder (with the 4 screws) be careful the screw does not "pop out" of the body and to thru the hole. I couldn't agree more... don't use 5Kg spools. If you do, make sure it spins very freely on your holder. To add to it the Makeshaper roll someone bought was wound horribly. The only reason we are using one is because its left over from the previous employees. The spool will sit a long time in the atmosphere before you can use it and risk absorbing moisture. Even printing things 100% every day it takes a long time to use it up. With Ultimakers nice material sensors we have changed 1k spools many times without affecting the print when they run out.
  6. I wouldn't call what we(robobartz) posted the ultimate solution- its just what worked for us.
  7. Ok we have solved this issue for our company and are 95% sure of what the two causes were: It may or may not apply to your situation. We were getting the error every 1/2 hour to 3 hours. Since we did this we have not seen the error in 2 days of printing. CAUSE 1 (80%) Our Ultimaker 5S is on a counter that is too narrow to allow the dual spool spindle in the back to be used. Therefore, we have separate spools on each side. At first we positioned, each spool on the side of the bowden tube that it used. In other words, if the PLA material is on the right, we put the PLA spool on the right. The PVA material was on the left, so we put the PVA spool on the left. The dual factory spindle(which we were not using) is in the center of back. Our side spools both feed from the outside in. This changed the angle/curve at which the material enters the material feed motors and possibly skewed the material away from the sensors. Therefore, if you have external spools, put them on the opposite side of the Bowden tube which the feed into, so the 2 filaments criss-cross in back of the printer. This will mimic the intended setup. CAUSE 2 (20%) We have a 5 Killogram spool left over from the previous employees. Our toolmaker made a nice plastic holder for it, however the axles he made turned too hard. So the feed motor (designed for a 1k spool) was unwinding a 5k spool with more resistance. We remade the axle to use a slippery undersized UHMW material and it spins freely enough to overcome the weight of the spool. Also the spool from a 3rd party was wound very poorly with criss-crossing strands and binding at the sides of the spool.
  8. We have the same error. I agree it should display which extruder it thinks is out of material. (even though neither of them are) We are getting frequent error: “One material appears to be empty”. The error is always wrong because there is plenty of material. This is extremely frustrating and making 3d prints take 5X longer because the error happens after we go home and the unit sits all night idle losing 10-12 hours of print time. Is this as simple as just swapping out the flow sensor? Looks like 1 screw & 1 plug. Here is what we have tried/observed: 1. https://ultimaker.com/en/resources/52577-flow-sensor-error 2. Upgrading firmware 3. Took apart and cleaned out the material feeder blew with light air (breath) 4. Blew out the Bowden tube to remove any residual dust. 5. Ensured the material is not binding 6. Measured the material: It is perfectly in spec at 2.85MM 7. Happens on multiple jobs 8. Message occurs at random time intervals ½ hour to many hours. 9. When the error happens it is using black PLA on extruder 1. Ultimaker brand PVA is in the other. 10. We are printing over the network. I wonder if printing using USB make a difference?
  9. I can print a part from Cura just fine on the USB. The printer is set up correctly with Ultimaker PVA (natural color) in the 2nd extruder. However when I try to print over network, an error message appears on the printer saying "Change material from PVA to "Natural PVA". First, you we can only purchase PVA from ultimaker. I'm assuming "natural" is the color, since its a throw away product it could be purple for all i care. Second, if "natural" refers to color, why does the network printing care what color PVA i have. I cannot find anywhere in cura settings where i specify the material. Please help.
