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…

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…

Stepper seizing with one axis controller

Hey all,Working with a 4x-23. Had an issue with the carriage stepper motor freezing up randomly. If I change the axis controller between carriage and mandrel, mandrel motor will seize up and the carriage runs fine. Problem seems to be tied to the controller and not the motor.Is there a software fix for this issue? Running everything at the suggested amps. Let me know what other info I can provide, I'm the new guy assigned to running this so I'm learning as I go. Thanks!

its very easy to reverse the polarity. See the attached image.

"Hi Vernon,
 
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…"

"HI Vernon,
 
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…"

Thanks for your reply, I did think I'd tried that with no luck, but will try again. What version of the software are you running?"

"Hi,
 
im using code, which rotates the mandrel CW and CCW:
 
M4 S20 C180 [clockwise rotation 180deg]
M4 S20 C-180 [counterclockwise rotation 180 deg]"
