@samantha I think this would require a note to be able to reject gears for broken teeth. I don't believe you could reject this part based on the call out for the diameter, will you look into this please?

Baldwin updated subscribers of T1584: Thermal runaway error.

@tutley @kent @karrad It appears the reason for the filure is due to the block being located too low on the nozzle shaft. The air from the extrusion fan system cools the block and causes the system to be over-damped (PID values were found with the fan not running.). The nozzle has <0.5mm gap between the nozzle flange and block but needs to be >1.5mm. This means the block is one full revolution too low. for this test i lowered the end effector to 3mm off the heat bed and turned the fan on all the way. The target temperature was set to 200C so it is clear to see the block could not reach the target and timed out causing the error. I will continue testing solutions and values.

Baldwin added a comment to T1571: Update printers to have newest parts.

@kent as I'm sure you'll find out if aren't already aware, parts can change. Even parts you think for sure won't. I would have waited to create a beta branch myself, but it shouldn't hurt anything. I myself would hold off on pushing files to the beta branch for sake of ease. To me it seems like more work than necessary with no added benefit. Also, doing this doesn't conform to the agreed upon form.

Baldwin added a comment to T1584: Thermal runaway error.

@kent @EricNugent I think we need to log the output from the thermistor, and overlay it with data from a thermocouple. Then we can tell if there is something wrong with the thermistor, and at what temp. We will be able to better determine a path forward with more data. I will look into a good way to automate this.

Baldwin added a comment to T1402: Extruder fan blower is loud.

@Steven @west Testing shows a significant drop in sound level between 1600Hz and 3000Hz using the new blower shroud. It looks as though we need to work on some other frequencies to bring our overall noise levels down. I will run some tests to determine the source of the larger spikes and work to reduce them.

Dec 1 2017, 1:04 PM · Yellowfin
Baldwin added a comment to T1386: Feeding filament.

@kenhara During development there was a feature to prevent that exact thing. However in some cases the feature interfered with the tension mechanism not allowing the idler to close fully. The feature was removed because that can cause stripping out of the filament. Also, you can always unscrew the tension screw, open the latch and insert the filament. However, this would require a slightly smaller spacer to set tension with. We decided to model the tension spacer to set tension before filament is inserted because with varying durometers of filament it would easy to over tighten if tensioned after.

Hey probably the easiest way to feed filament into the v3 is by cutting the filament at a 45 (liek you suggested) then put it in as far as it will go, then use your thumb and/or fingers to manually advance the large extruder gear. Once the hobb teeth bite on the filament, you should be able to let go of the filament and just feed it the rest of the way through manually with the large gear.

Hope this helps.

@karrad Ran a test moving a carriage from the same location (100mm) +175mm with both step values. As expected the 100.5 step value overshot the target (275mm) nearly 1mm, while the 100 step value lined exactly. In my opinion, if we can see this difference on a machinist rule this is too much error to have present in any axis.

Baldwin added a comment to T1379: Right Z guide rods misalignment.

@kent The assembly was done in accordance with standard techniques, however the sheet metal was modeled incorrectly which is why it does not line up correctly in the assembly. To my knowledge blender cannot set a coincident constraint. If you look in the old assembly you will notice the upper and lower plates are wider than the inside of the left and right flanges in which they are supposed to rest. Therefore these are not properly aligned. In order to align the left and right sides coincident constraints were applied to the front of the upper and lower plates. There will still be a 64um overlap on the back side until we are able to correct our solid model for each sheet metal piece, but everything lines up across the YZ plane now. The prints appear to be correct, but i couldn't find a call-out for the distance between the flanges on the left or right plates. Due to the nature of sheet metal production i feel we should be cautious if we decide to change the prints. If anything just a note in the rev block notating the change to the solid models as suggested by @samantha .
