VC4 500 IDEX - 125hz Peak
Or maybe I have work reprint them on the old stratasys. Probably cost $100 USD in their proprietary model and support material. 😂

Reprint would be the easiest test.

VC4 500 IDEX - 125hz Peak
I’m curious if the belts being anchored in plastic parts with possible issues may be contributing to the noise. Tempted to reprint parts on my Bambu and see if that helps, or maybe redesign some parts to have the machine/fab shop at work make me some more rigid components.

VC4 500 IDEX - 125hz Peak
Z belts don’t move like XY belts though, so higher belt tensions won’t generate the same heat buildup in a z bearing like they would an XY. Also depends on the wrap angle of the belt.

VC4 500 IDEX - 125hz Peak
The stubby gantry sounds interesting. I think I would much rather look at sourcing some carbon linear bearings though. May have to do that in my free time and model some designs and run some deflection calcs to see what would work for a 500.

VC4 500 IDEX - 125hz Peak
I will have to give this method a try next week. Boss realized what a mistake it was to say print slow as is when the print time said 62hrs for less than 1 kg of material used. 😂

VC4 500 IDEX - 125hz Peak
Because of the long lengths, I have been curious if an additional idler or intermediate tensioner would be beneficial to reduce the slap on the 500 configuration

I’m looking forward to seeing some more official trouble shooting guide for IDEX also.

Messy Y graphs
It did a bit. Still noisy, but I can’t find the culprit and boss wanted to get parts made, so I just slowed down accel to 4K and it is working.

Messy Y graphs
I haven’t run the belt tension again, but it sounded like the bearings in the y carriages, so I removed them and packed as much grease as I could into them. Evidently I didn’t do it good enough the first time. It got rid of the peak on the shaper graph, but it is still a mess.
Shortening wires on the tool head now. Should be running another test in a few hours.

Messy Y graphs
So I took a leap of faith that it was carriage binding. Loosened the right Y rail, both Y carriage plates, and all the T nuts to the X beam.
Idler/tensioners were unequal distance from the rail, so I made them equal and let out belt on one side until the Y carriages were equal distant from the rail and then tightened everything back up. Now relative belt tension graphs are having me adjust the belts to where the Y carriages are uneven again and actual belt tensions are very different.
Gonna try to loosen everything and even the idlers and belts again.

Regular surface distortion pattern towards end of larger first layers VC4
I am curious how carbon rods, like the Bambu P1/X1 series would do. 500 is a significantly longer span and more weight, especially with IDEX.

The advantage to the Ti tube is the weight reduction in addition to the other benefits. Adding titanium and hardware only makes the stock beam heavier.

Have to see if our suppliers can get the material cheaper than online metals. To get a 1200mm long sheet is more than we spent on the entire printer kit. 😳

Have to see if I have any issues with the VC4 500 at work once we start printing. Maybe I can convince the boss to buy a small sheet to laser cut some backers from and test.

Curious if titanium backing plates would help? I know they are used by the Voron crowd.

A setup similar to Bambu’s would leave plenty of room for airflow.

If looking at exotic options, may be worth looking into a carbon beam or dual carbon rod setup like Bambu is using on the P1 and X1 series printers.

Strange Heightmap Shape
Looks like a very tight range. You should be able to get the back left corner down with minor adjustments to the back leveling feet, if you want. Maybe a quarter to half turn should do it.
