tutley updated subscribers of T4910: Extruder 1 Harness interfering with bumber.

@kent there is some room behind the motor, and @west and i were discussing the possibility of running the cables here. The issue that comes up is that the cables will likely be rubbing on the x rods during printer operation

tutley added a comment to T4493: Determine if using Igus tool head motor mounts.

I would definitely recommend the igus mounts over the delrin mounts as the cost of the delrin mount is significantly more than the igus mount. Also the holes were not parallel in the delrin which was causing binding issues. The igus mount seems to work much better and looks nicer.

After looking at @logan 's machine, it does seem that the bow on the archim is a bit excessive. There is some concern because once the drivers heat up this will potentially bow worse due to thermal expansion.

Fri, Nov 30, 7:30 AM · Quiver
tutley added a comment to T4756: Heatsink bows archim.

@logan how much are they bowing? i think a little bit of bow is normal as we want the heatsink/thermal gap filler to be sandwiched between the board and chassis for good thermal conductivity.

Fri, Nov 30, 7:28 AM · Quiver
tutley added a comment to T4755: Fitting heatsink in frame requires hammer.

@logan Eric may be able to adjust the slice to compensate for this. The fit needs to be tight though so they dont end up moving around and shorting anthing out, but if it is requiring a hammer that is too tight

tutley added a comment to T4757: PP-MP0157 fit around stand-offs.

@logan if you install it as a full assembly you should be able to install without a flashlight or tweezers. the ESD/EMI gasket holes are supposed to be tight on the standoffs for good electrical continuity

tutley added a comment to T4718: Remove built in supports from printed parts.

@logan it is not a problem if he uses .38 layer height on the parts with built in support. the biggest problem i have encountered with cura supports is that they often have trouble adhering to the bed and then break free mid print and spaghettify. They usually build enough spaghetti to correct the supports and it often works out, but not without loss of print quality. Also i have seen the parts warp off of the cura supports a lot

Wed, Nov 28, 8:27 AM · Quiver
tutley added a comment to T4718: Remove built in supports from printed parts.

the built in support is not more difficult to remove than the cura supports and works better (in my opinion) if sliced properly. To my knowledge all built in supports are made for .38 layer heights. If the desired layer height for production is different we can adjust the distance from the built in support to the model.

Wed, Nov 28, 8:17 AM · Quiver
tutley added a comment to T4716: Production jigs.

on that small part with the M5 insert you have to be sure not to force it in too quickly or it will deform the part

tutley added a comment to T4502: Mask all the threaded holes on the bedplate..

@kent i think the biggest issue with putting a masking dot on every hole is that the cosmetics will be negatively affected.
I see no reason that this would cause mechanical or electrical issues, however it could potentially introduce EMI/ESD issues.

Tue, Nov 20, 1:12 PM · Quiver
tutley added a comment to T4501: Make clip in switches.

While i like the design and i think it would work fine for normal printer operation, I do have one major concern with it.
Due to variance in printed parts, the fit of the switch in the part will be variant as well. The switch is not rigidly mounted and is essentially floating, so the repeatablility of z homing will likely have a lot of variance. In normal printing this should be fine, but in the case that someone has a failed print, and is able to get the coordinates at the point of failure, they would not be able to resume the print due to the poor repeatability of a floating switch.

tutley added a comment to T4490: Toolhead actuation system is overconstrained..

@kent the holes in the motor mounts we got are too small. they do fit the rods, but the friction of the delrin is too much. We have some igus bushing type motor mounts coming that should work really well.
The delrin motor mounts we have on hand will need adjusted to a larger diameter hole otherwise the drag is too much. I have ordered 6.05. 6.10, 6.15, 6.20, 6.25mm drill bit for this.

Nov 16 2018, 8:56 AM · Quiver
tutley added a comment to T4490: Toolhead actuation system is overconstrained..

@kent if the tolerances are tight enough on the rod spacings and loose enough on the motor mount hole diameters, then we shouldnt run into issues. The big problem we have seen with first articles is that the back plate is bowed so when the top and bottom plates are attached they lean inward and that puts the rods out of parallel.
