oliver added a comment to T6604: AS-PR0096: Mini 2 X-carriage having too much drag on the x-axis.

@tutley As far as MER is concerned we have not heard of any changes, though I was told that they are no longer using the force gauge to check the drag on the parts in cluster.

oliver updated subscribers of T6771: Where will Quiver USB sticks be copied.

@DaniAO We still have the old USB flashers in MER and it might be easy to continue flashing them in calibrations as I can't think of any reason Pre-sub might need them and I would rather keep the number of inventory movements reduced. @tomc may be able to share some insight on any other products that might be using them.

oliver added a comment to T6582: Vernier model seems deceiving.

@tutley I thought we were leaning towards having people use flow rate to calibrate their extrusions and not e-steps due to the limitations of not being able to adjust the 2nd extruders e-steps. Also if that is true then is there a way to adjust the flow rate through the machine instead of slice settings?

I can confirm that the aero tool heads will see a spread of e-steps values ranging from 410 to 430, give or take a bit more or less, from working in cluster.

oliver added a comment to T6614: Add MIN_TEMP and MAX_TEMP test to electronics box testing rig.

@kent So the table on the link you provided doesn't actually have any resistance to temperature settings, they have a single temperature at a single resistance for several different part numbers, I was looking at that sheet when I had to redesign the sheet we use for resistance. I believe it's the temperature and resistance that was used in order to calculate the beta coefficient because it seems that most companies don't actually use the stein-hart equations. My numbers may still be a bit off because they do include some error calculations as requested by E3D.

oliver added a comment to T6614: Add MIN_TEMP and MAX_TEMP test to electronics box testing rig.

@kent Here is the sheet that we use to check if the thermistors adjusted for our own tolerances as set by us and E3D using the stein-hart equations. They also do include a b, beta, value that was obtained from the manufacturers site.


The last sheet as some input spells where you can input a specific temperature or resistance and it will solve for the other.

oliver added a comment to T5073: False positive reading from filament sensor.

@matth I can confirm what @anolen is saying with my own experiances. Anything you can do to reduce the drag on the filament and reduce the chance of the filament stretching will help a lot.

oliver added a comment to T6582: Vernier model seems deceiving.

@tutley I think my only question I have is, do we want to continue keeping the circles to the same tolerance? Do we want to maintain it at around 9.8 to 10.2mm for the circle?

Mon, Apr 15, 3:22 PM · Quiver
oliver added a comment to T6582: Vernier model seems deceiving.

@anolen Just to confirm, we have only been measuring the top section of the round post. Also ngen was used on TAZ 6 but we also didn't have any dimensional tolerances for TAZ6 prints, so that should be kept in mind as well.

oliver added a comment to T6604: AS-PR0096: Mini 2 X-carriage having too much drag on the x-axis.

I just put one of the ones that production failed out for being too tight on to the mini 2 on my desk and did not have any problems with a large amount of drag.

oliver added a comment to T6604: AS-PR0096: Mini 2 X-carriage having too much drag on the x-axis.

@tutley One of the issues I found is that when the reamer is hitting the metal plate serve as the bottom, it will 'skip' along the bottom and cause parts to come out crooked. I noticed and informed the cluster techs to make sure that they are not hitting the bottom of the plate when they are putting in a new jig. A worn out reamer will cause those issues as well, so the reamer has been swapped out and they should be dating them from now on.

oliver added a comment to T6544: Need source for bed washer standoff HD-MS0287.

@samantha Here is the control chart for the bed washer stand-offs. I arbitrarily assigned a the control limits to be 9.9 to 10.1 mm for now. Based on the amount that was measured and the distribution, we are seeing a fall out rate of about 9%, with a mean height of 9.97 mm.

oliver added a comment to T6582: Vernier model seems deceiving.

@tutley We can't calibrate the extrusions, so is this something we would have to just accept? Fixing this issue would mean having to adjust the flow rate, which would mean a separate slice for each printer we calibrate which isn't very feasible without changing the FW to allow the calibration of each individual tool head.
