Could you take a pic of the effector from beneath? I got my nimble installed I’m finding that one the washer/nuts protruding from the bottom interfere with the heat sink fan installation.

I'm not going to be in town until Monday. If Is not to late I will post some pictures when I get home. If I remember correctly I have the heat sink fan mounted up side down for the same reason. I have to double check.

This is the way I installed my heat sink Fan. I did file a lock nut to have room for the heat sink fan. Please let me know if you need any pictures from a specific angle

Yeah, mine's pretty much the same way but flipped because mine's a v2 effector. I ended up modeling a fan duct for the hotend that completely cuts off one corner and it clears fine. I think I'm going to switch to m2.5 button head screws and fiber washers from the bottom and that should clear better.

Hi Blt3dp. Just checking to see how you've gotten the Nimble installed. Are you happy with it ?

I ended up getting some m2.5 button head screws, some fiber washers and half height nuts. I installed them from the underside and used locktite to install the nimble adapter. I can now use the official e3d fan shroud. I have almost 2 mm of clearance. And the nimble itself is awesome, I think it’s a great piece of hardware.

After so much time I finally was able to print with success some models . ( See the attachments). Until In this morning when I try to calibrate the printer and I noticed that the printer Is start skipping some calibration points.I also noticed that when I home the towers the hotend Is moving to the left after homming.
I'm doing something wrong ?

I noticed something similar with mine. You might check to make sure your hotend isn't coming loose from the effector. I noticed my hotend wobbling during a print. Turns out the nut holding it tight to the effector had worked it's way loose. I paused the print and tightened it up and was able to finish the print. Then I went back and put thread locker on it. I haven't had the problem since.

Thank you blt3dp for your help. I checked the hotend and isn't loose. Everything looks fine

There haven't been any changes to the machine have there?

I'd check all the usual stuff like the condition of the belts, I at one point had a belt fail where a section of it was stretched and the teeth were super far apart, probably too high tension. Check their tension too. Check to make sure that the pulleys are still tight on your motors, they've been known to come loose and semi rotate around the shaft.

I suppose it could be adjusting the position due to the calibration, I would watch it when it calibrates. If it skips some points, watch it to see if it triggers either too early or not all. Maybe that will give you a clue on what's going on.

Thank you for your help. I checked what you said and everything looks good. I tried to calibrate with the hotend and bed off and it worked. Where do you think it is the problem ? Thank you

I'd probably check the cabling to the effector again.
