tutley added a comment to T1565: Filament jams on cluster machines.

@karrad i modified one of the filament constraints to have an 1/8th inch inlet hole (3.18mm) and was able to remove some swollen filament no problem. The same filament jams in the standard constraint. Also i am printing with ninjaflex right now. I will let you know how the print looks tomorrow, but we might be able to just hit all the iinjection molded filament constraints with a 1/8th inch drill and prevent the filament jams.

tutley added a comment to T1565: Filament jams on cluster machines.

@karrad i can contact E3D about this issue but we have seen this occur since we started using the aeros. Based on my investigation into this issue, it is happening entirely because the inner diameter of the heat break (~3.2mm) and heat sink (~3.2mm) is a larger diameter than the inner diameter of the injection molded filament constraint piece. This is a side affect of having a toolhead that can print both rigid and flexible materials. The inlet of the constraint peice is right at about 2.97mm diameter, while the outlet of the constraint peice is 3.35mm diameter (its conical). When the filament cools to the form of the heat break and heatsink it is then too large to pull out of the inlet hole of the filament constraint. So, if you heat the filament up and extrude a small amount (whatever was in the heatsink/heatbreak) you can then easily pull the filament out. This is why we are telling people to remove their filament at extrusion temp after a small amount of extrusion.

tutley updated subscribers of T3146: Y cable chain influencing Y axis binding and bushing wear.

@logan that may be true, but i discussed this with @bowman and he remembers them as being used to level out the y axis. He and I both dont ever remember them being used for y cable chains

tutley updated subscribers of T3146: Y cable chain influencing Y axis binding and bushing wear.

@EricNugent You are coorect that there is an upward force from the chain on the y bed plate, however the amount of upward force is very slim and i dont think you would see noticeable wear from this in the lifetime of the printers. Also the weight of the bed plate and heated bed etc applies a downward force so they do cancel each other out somewhat. The shims used were not to alleviate an issue with y cable chains, it was to level out the y axis due to issues with sheet metal. The minimum bend radius for the cable chain used is 28mm or a 56mm diameter. The chain is mounted in a gap that spans ~72mm so there is a lot of margin before we see forces from exceeding the bend radius of the chain. This chain is not really overkill for the job as generally you want at least 10% of the volume in the chain to be free space, otherwise you see a lot of broken wires like we saw in the foxglove chains. Also I do not think rotating the chain would help as it would increase the amount of torque on the y bed plate which will cause uneven wear on all 4 y bushings and increase the rotational slop of the y axis.

tutley added a comment to T3090: Installing toolhead increases carriage drag.

@kent after our investigation/discussion on friday, we found that this might be able to be corrected with a flexy gasket or something similar for the x bearing holder. Maybe just going to 3 screws too. We were able to alleviate the added drag from the toolhead installation by loosening the x bearing holder a bit. We are seeing when tightening the x bearing holder (the top left screw in particular) that we get a lot of added carriage drag. These two printed parts are not always laying flat against each other and this is causing issues with bushing alignment/carriage drag. I will look at some ways to alleviate this issue

tutley added a comment to T3090: Installing toolhead increases carriage drag.

@kent i think it is a combination of things. Some of the added drag is due to the downward force from gravity on the overall heavier carriage. Also the toolhead is cantilevered off the axis a bit and applies a torque on the whole carriage. Also with how the toolhead is mounted, when tightening the screws tight, there is potential for distortion of the part which might change the alignment of the bushings in the bore

@logan we can adjust the outer pocket to be a bit smaller so the nut stays retained. Also i was thinking we could print a little insert that goes in after the nylock to hold it in place. I dont think it is necessary now, but if there are a lot of issues with the thicker belts, we might be able print some adjustable tensioners with different gap spacing to accommodate the variations in belt thickness.

Also @samantha and i were able to pull 100N on the belt and there was no slipping. It was a new belt however so the teeth werent compromised. If you are having issues with tooth engagement and slipping i would recommend new belts be installed.

tutley added a comment to T2634: Initial Profiles for testing.

@DRobertson @anolen @karrad I dont think we should be printing at .25 layer heights with a .25 nozzle. This is generally seen as bad practice. I have mentioned it before but once you have a layer height that exceeds 80% of the nozzle diameter, you start sacrificing adhesion to previous layers. I would be willing to bet the parts printed at .25 layer height on a .25 nozzle are extremely weak.

@benmalouf @karrad We can make changes that dont impact the functionality or cause critical dimensions to change. The fan shroud in particular will be a tricky one to change since we need to avoid altering the air path or it can impact print profiles. Originally in the prototype review i had a separate fan shroud for each toolhead that designated the nozzle diameter. A feature that myself and many others liked. I was told to remove this so that the same shroud and extruder mount that are on the aerostruder v2 standard toolhead can be used for achemon to make things easier for the cluster and internal reference etc.

tutley added a comment to T2950: Y-rods loose axially even with screw at full compression.

@kent this is only true if the rod is fully seated in the y idler and the sheet metal is perfect. The intent of the design is to level out the bottom plate flanges so the belt rides in the correct location on the y idler. We never see belts ride too low, when theres an issue they are always rubbing on the top of the idler which means the flanges are bent upward so tightening that screw allows an adjustment to level things out
