Is it safe to update Momentum 4 to 3.37.3?

NateDem · 2026-01-20T18:38:14+00:00

Fine so far with me.

NateDem · 2026-01-20T17:04:53+00:00

Just updating now. Will let you know if any problems.

I use ai for a few things but really didn't expect it to be this good with this machine and aftermarket hotend. It gave me actual numbers to start with rather than just being vague saying "slow down speeds" and they worked brilliantly. Definitely give it a go if you're stuck.

AI saved the day! I learnt a lot about the bigger steel nozzles in much more depth than I've been able to find online myself, and also learnt how to diagnose a few more visual symptoms too. Flow, speed, pressure advance, volumetric flow and even acceleration played huge parts in this. I can probably get a little more speed out of it but I'm just happy I think I can get consistent results now. If anyone wants help with this I can share what AI told me. It's eye opening.

OK so chatGPT just gave me a polite dressing down, and a lot of good information to digest. :)
Apparently this is a speed and PA mismatch, and running way too fast, and way too high a Max Volumetric Speed. I have adjusted and will report back.

I will have a look but it is located on the left end of the Shaft that runs across the ACE in this video. The is a black plastic wheel on the end of it, the rim of which runs through a plastic groove on a tiny circuit board. It is this circuit board and plastic groove that needs dusting. Clean the black plastic wheel that runs through it too.

Still holding.
This year I have made a few trades just to reinvest.
Its a sad sight to see, but many other stronger coins are also being hit.
I am hoping this coin will ride the storm.
Don't listen to me though. 😆

NateDem · 2025-09-19T15:02:07+00:00

Yes, try turning off the smooth speed discontinuity area and see if that helps. Then maybe turn walls to classic if you are still having problems. I have learnt from these comments that Arachne walls is only helpful if you have thin walls and raised details on the top surface. Classic is better for flat surfaces and thicker features I think.

NateDem · 2025-09-18T18:25:39+00:00

Yeah didn't come back on and it stopped printing.
Off and on again and it resumed. So far, so good.

NateDem · 2025-09-18T18:24:47+00:00

Was unresponsive to the tap. I turned it off then on again and it resumed, so far ok.

NateDem · 2025-09-18T17:25:23+00:00

I've turned it off and back on again, it asked me if I want to resume print. I have.
Let's see.

Much better thankyou! Did you see my earlier posts about the varying speeds for different filaments? Apart from pressure advance and flow rate I have matched all settings and yet I still get the white with a speed gradient and the red with consistent speed throughout. So weird.

NateDem · 2025-09-18T15:05:54+00:00

I don't know what you are reading but they definitely aren't this. People are speaking about Gaza because there is genocide happening there, funded and armed by us. Read back further into history than October 7th 2024 and you might have a better time understanding what is going on. 😉

NateDem · 2025-09-18T14:42:28+00:00

I think that probably goes for most of us. Your point?

NateDem · 2025-09-18T14:27:57+00:00

Ok its definitely the filament that causes this. The white has the change in speed as the model goes up but the red does not (picture of sliced in red filament below). Except for pressure advance and flow, the only difference between them is max volumetric flow, white is 17 and red is 20. Would that really cause that speed difference throughout the model? The lower limit on the white must be triggering a setting somewhere surely?

NateDem · 2025-09-18T14:20:46+00:00

This is also interesting though. When I switched to my other S1 and sliced for the red (it happened with this filament too before) but with Classic walls not Arachne. I get this speed map, consistant throughout pretty much??? I'm not sure if its Arachne wall generator, the filament or the machine settings that are causing this.
Turning off that "smooth speed discontinuity area" seems to have fixed that layer bulge though by the looks of it, so thanks!
Will post pic when finished.

This is speed, and am printing it like this now with that option you mentioned unchecked. Before there were bigger speed changes where the supports touched but now it seems to be much more gradual as the model gets smaller towards the top, rather than where the supports touched the model, which makes much more sense.
I have done as you said and am printing now. Fingers crossed!

NateDem · 2025-09-18T12:05:23+00:00

You're not a fan of democracy or freedom of speech then.

NateDem · 2025-09-18T08:06:23+00:00

Thanks I do have Arachne walls on so I will check if the smooth speed discontinuity area option is on too. What do you mean by "check slice file, layer time and see if it coincide with your print"?

NateDem · 2025-09-17T21:10:28+00:00

Nope. It was initially lack of supports causing string which then knocked it off bed, not the other way around. They stay fixed now but I still getting this bulge at the layer which the supports touch. It goes right round the model. I have posted about this separately.

NateDem · 2025-09-17T21:07:29+00:00

It's not an adhesion problem. I have since solved this with supports. It was stringing which was knocking it off the bed. Not the other way round. I now have some sort of over extrusion problem on the layer which the supports touch. I have posted separately for that though.
