Hello everyone,
How have you been going with winding angle selection? I understand the 90’ is optimal for burst strength (which many of you will use for rocketry), but I am generally trying to optimise bending stiffness. I started out using all 45’ p

I'm excited to finally have our machine up and running and winding mandrels, but would really love to hear guys experiences in the resin ratio / viscosity used, and how to control the layer thickness.
For our first pipe I used a low

I am trying to create a 45-degree 2-axis layup in 3-axis mode. The 4-axis winder that I am working with has been having an issue where the dwell times are different on each end
Read more…Hi guys, we just got our X-Winder (Prague) and have the same issue as many - tow is slipping at the ends of mandrel even with maximum rotation of 230 degrees. We were thinking of adding plate of same diameter as mandrel with pins at both ends of mand
Read more…is there a calualtion or table where is can figure out the thickenss of different degree completed layers. like i have incountered that 12k tow at 75 degrees is .48-.55 mm for a completed single layer. this would be really helpful when trying to deci

I have been having extensive trouble and been trying to get my 4-axis X-winder up and working over the pa
if I'm wrapping a oval shaped mandrel thats about 80mm by 30mm what do i set at the mandrel size in the software? 80mm? or do i have to calculate the circumference?

Its my first post here, so straight to the point. I have been lurking here for a while to find more user reviews and opinions about this great looking machine. Reason why im still waiting before buying one (money of course

Has anyone else encountered an error with the delivery head were at a random point in a wind sequence it will just ram the payout eye into the mandrel and drag it along to the end of carriage axis? I have checked the g-code and cant find any error

Explain what the parameter A means in each frame of the G code please.

I made this roller gluing two concave rollers and washers. This helps keeping the filament centered. I was having issues with the filament slipping out of the flat roller and getting stuck in the side.
I'm thinking on buying a 3D printer and making
Read more…Hi there
I was wondering if it is possible to adjust the transition speed at the ends of the winding. As the ends tend to slip I am thinking a slower Transition from 45 to 90 degrees at the ends may improve this problem.
Any thoughts on that?

I use XW-2 and have a problem that I hadn't managed to solve. The end winds slide down of mandrel when the carrige changes direction. How can I fix the plies?
My ideas as follows:

The upgrades to the new 2 and 4 axis models look great and I am looking to do the following upgrades and was wondering whether anyone had some feedback on these proposals or had thought of doing something similar?

i just assambled the Xwinder and startet runnig some tests.
Now there are some issues with die DHR axis. Firstly on the drawings tabbed ring for locating the axis seems to be at a 45° angl towards the roller which isn't possible if the holes a

I recently received my 4 Axis machine and am eager to get going with it. I have it set up on 12' long bars and have a few questions from the community.
1. I have noticed that my set up has a decent amount of torsional flex and sag. I will
