Hey,

I am using the 4.16 version. As the carrier reaches the left and right ends of the mandrel, the DH does not advance to the left or right DH advance point. It stays at the DH Offset from mandrel surface. After the [CW ELLIPSE AT LEFT END] move, I then get the error shown above. This repeats until I stop the wind. However, if I pause the wind at either end during the wind, after a minute or so, the DH will advance to said point. 

If anyone has any comments or suggestion,…

Hi there everyone,

 

my buddy and I have started doing trial winds for our composite-overwrapped pressure vessel with 3D printed mandrels, just to get the hang of the machine. 

BUT we are having problems - does anyone know a fix to these? 

1) The DH rotary or the DH linear motor do not respond to software inputs and don't move sometimes (not even when when winding - sometimes even when we just say "go home"). At times, everything will work fine and then…

Error type Mismatch 13 and wrong directions

Hi everyone, I am using the XWinder for more then 2 years and I am actually facing a big problem... Last summer I have done the update of the software from the version 16 to the version 22 and the programm I was operating stopped functionning correctly. The problems were that while running the programm, all the steps were upside down which means that when the carriage was supposed to move to the right, it was moving to the left... However, the manual operations were working correctly and also…

Rotate Mandrel in CCW direction

I can't get the mandrel to rotate anti-clockwise. Have tried M3 and M5 and also a S-70, none seem to work. M3 still did clockwise, M4 does clockwise, M5 stops the wind, M2 isn't recognised. Any help please, have changed my head setup and would prefer anti-clockwise winding. Only option for now is to somehow bodge the motor the other way around! Thanks, Alastair

Using Variable/Macro Programming

Hi All, New to the forum having recently bought a 2X-23 winder, not new to filament winding, so was trying to write my own g-code files and use incremental values for things like layer count so I didn't have to have a very long g-code file. Unfortunely it doesn't seem to like my variables or the WHILE/DO/END commands. anyone know if it's possible to do this or am I barking up too complex a tree? Thanks, Alastair

Wrapping Composite with Shrink Tape

Hey all, we have been messing around with our 4X-23 machine and have had a couple successful winds. However we have been having an issue with our shink tape layer.You can see in the pictures below, we are getting these weird voids/pockets when we apply the shrink tape. Its almost as if the tape is buckling on itself as we wrap it.Is this caused by us wrapping the tape too tight? We do wrap it tight but not entirely sure if that is the issue. I guess what I am asking is what is the proper method…

"It was 70€/kg of roving. On one spool, there is 1,2kg of carbon roving, together 5 spools, 420€. It is 6,4mm wide and a work with it is also good:)"

"I checked out that sigrapreg and it looks great. Love the varying cure temps. Doesn't say too much info on all resin types they have available. 
How much did you pay for the 6kg spool? 6kg is not a bad minumum order depending on the price of course.…"

"Hi Curtis Kent,
If I am not mistaken, you have heat shrink tape from dunstone. Depending on the film thickness you can only overlap the tape half it's width. For expamle if you have a 1" wide shrink tape and it's thickness is 0.002" or more, I would…"

M4 seems to work continuously if I don't put a specific rotation angle, unfortuntely it automatically rotates clockwise. The problem then with putting a specific angle is that it completes this before moving onto the next command! We're…"

Vernon Hultzer replied to Alastair Barnett's discussion Rotate Mandrel in CCW direction
"Alastair,
 
From what I understand, the M4 command is a non continuous rotation command, so this means that you have to put an angle of rotation.  You could try a big rotation angle, like C=3,600,000, which is 360x10,000 (10,000 rotations), then use…"

Great, so I got the mandrel moving CCW, with the M4 and negative C, but under a G1 the negative C doesn't work and I can't get it to rotate continuously CCW using the M4, so struggling to get CCW mandrel movement while moving the delive…"
