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

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

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

We're currently working towards setting a speed record for a collegiate rocket launch at just over Mach 4, and a huge part of that is

I have worked with this winder for few weeks now. I'm still unable to get DH Linear to work properly. The problem seems to be that the executor software doesn't recognize the position signal from the motor. If i check "Help"-> "about"

I have been having extensive trouble and been trying to get my 4-axis X-winder up and working over the pa
Hey guys, we tested out a few new mods to our machine, and had some great success with our last wind.We removed the plate/roller/lucky band squeege system as it was proving inconsistant.We made a new bracket for the squeege roller, out of two 90 alum

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 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:
1. to change a winding angle at the end of the mandrel, I me

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

My X winder is by far the best machine in my workshop. It works straight out of the box, makes high precision parts and also looks pretty neat. Being a tinkererer with a 3d printer though, means I was always going to make some modifications. Today I
