After providing spare hands to tgreer in trying to get the new controller wired in for the open-day, I noticed both motor connector plastics are extremely perished. Sockets and plugs. The Y-axis (?) stepper connector has previously been bodged. Pins no longer make good electrical contact with bodged SIL connector. This is both due to bent pins that have apparently been forced, but also the SIL socket terminals sliding freely in their plastics. Pins on stepper are also able to move into the motor body when pressed! Attempting to press another connector onto them will likely push them all the way into the motor housing, rendering the motor useless.
G21 set units to mm
+
As the motor pins still pass continuity tests, this severely damaged connection seems the likely reason for the motor skipping phases.
G28 home
+
My recomendation is that flying leads are soldered directly to the damaged pins and connected to a seperate connector that can be fixed to the chassis. Possibly a DB9.
G90 set absolute distance mode
+
Replacing the steppers entirely is a possibility, but will be tricky due to the capstan-drive. Removing the stepper will probably mean re-winding and re-tensioning the system.
G91 set incremental distance mode
 
 
M101 extruder on
 
M103 extruder off
 
M104-108 extruder temperature control
 
M110 filament height ?
 
M113 duty cycle ?
 
  
*Write translator to perform the above conversion
+
The capstan drums seem at risk already however, as the (nylon?) coating on the steel cable is severely deteriorated, cracked and flaking off. Once the coating fails sufficiently to expose the cable, the cable will begin to eat into the surface of the aluminium capstan drums, ruining them. The drums are not likely to be easily replaced, the motors and cable are.
  
==DONE==
+
While the cable is fine for testing use, if the Statasys is going to be used frequently, new cable should be sourced as a priority.
* Power up normally.  Are there any bad-looking lights on the front panel?  If so, something is stuck.
 
  DONE! - It's fine.
 
  
* Power up with left and right buttons pressed, should start self-test run.  It will loop, power-off or hit reset to stop it.

- Sci
  DONE! - It works as expected. Ran through all the self-tests, and they came out ok.
 
  They're all in the service manual. Have a look.
 
  
* Connect the serial port up.  Document how to reach it on this wiki page.
+
===27-11-2013===
* Open her up, document the position of the switches on the back of the automove unit.
+
The milled parts should arrive any day now and, once installed, we should be ready for a first test print.
* Determine serial parameters from the dip switches, see page 9 of [http://www-car.asymtek.com/support/manuals/70_0045_20_C.pdf the automove operation manual].
 
  DONE!  [[Equipment:Stratasys_FDM_1650#COM1_Settings]]
 
  
* Using [http://www.nordson.com/en-us/divisions/asymtek/documents/manuals/76_cs02_01_acl_manual.pdf the acl docs], find the current values of the personality parameters, document them here.  This will hopefully keep us from losing them by accident later, and tell us a bit about how the machine is set upYou'll want the OP command, page 3-50, and the list of personality parameters, page 14-1.
+
As far as I am concerned, based on the investment by members, a successful print of any description, using both extruders or not, is proof of workingHaving experimented with Dual Extruders, the configuration too complicated to include this by the (self imposed) deadline.
  DONE! [[Equipment:Stratasys_FDM_1650#Initial_Conditions]]

*Moved out of alcove and tried a few basic things.
 
*Self-test ran (aborted) after restoring front panel connector.
 
*All axes capable of movement using arrow pad.
 
*Remaining parameters dumped and entered in wiki
 
*Feed Home command works
 
*Z home using buttons appears not to stop (aborted, looked dangerous)
 
*ACL manual reports that microstepping is used (but is that for a different controller ?)

However, as I mentioned on IRC, if we cannot have a completed print by Christmas, I think this project should be marked as 'not completable' (if there is such as word) and we call it a day...

Hey all.
  
==Current status - 2011-07-01==
+
Right, finally got time today to do a thorough check-up on the stratasys. As I have rpreviously said, all internal mechanics (including the steppers) are in full working order, especially as I performed a strip and clean to it pre-move.
  
The rackmount machine on the floor is now running XP again; somebody, likely Billy, reinstalled the system without updating this page.
+
After a quick talk with Ian on Wednesday, I have traced all the cables and found all the documentation for the parts, ferrous detecting end-stops, x-y controller pin outs, steppers etc. I have removed the old and power hungry heaters and flourescent lights.
  
I've installed speedfan, and disconnected some of the non-software-controllable fans.  This makes it somewhat less horribly loud.
+
I have paird the stepper cables and made ready for the 4-wire board. Also gave another clean
  
I've also started documenting the initial parameters below.
+
Basically it is ready to be connected to control board and ready to run.  
  
The correct serial settings are 9600 7E1 (that is, even parity, 7 data bits, 1 stop bit). Other settings work, but ESC.E gives errors.
+
All we need now are to nice tourqey nema17 steppers, 2 j-hotends (ian has offered to source and will start pledge, less than £100). Once these have turned up and I've cad modeled them, i will design a nice clean and easily accesable mount for them in the existing hot end housing (also been cleaned).  
  
==Current status - 2011-06-23==

Charles will need to add a ACNode and it'll be up and running as a tool for the space. But like the laser cutter and charles, I will be its main care-taker/daddy lol.
  
The rackmount machine on the floor under the terminal to the right of the stratasys is named capak (the man who coined the term "robot").  The user is hackspace/hackspace.  Please use sudo for root.  (The root password is also hackspace.)

Hope this has cleared up any concerns or apprensions about having a fully working, accurate, industrial 3D printer in the space to be used by people with training.
  
If you know why the monitor is nigh-unreadable, please fix it.

It's kind of functional.
 
 
 
There's an computer connected to it and we can get a serial port connection on COM1.
 
 
 
At the moment it's only returning error messages.
 
 
 
The automated tools can connect happily.
 
 
 
IT STILL NEEDS CALIBRATION BEFORE USE!!!
 
 
 
Please do this first, and let us know what happened.
 
 
 
There are two printed manuals, a printed service manual, and the rest of the docs are on the desktop in the Stratasys folder.

1-6-2014

After providing spare hands to tgreer in trying to get the new controller wired in for the open-day, I noticed both motor connector plastics are extremely perished. Sockets and plugs. The Y-axis (?) stepper connector has previously been bodged. Pins no longer make good electrical contact with bodged SIL connector. This is both due to bent pins that have apparently been forced, but also the SIL socket terminals sliding freely in their plastics. Pins on stepper are also able to move into the motor body when pressed! Attempting to press another connector onto them will likely push them all the way into the motor housing, rendering the motor useless. As the motor pins still pass continuity tests, this severely damaged connection seems the likely reason for the motor skipping phases. My recomendation is that flying leads are soldered directly to the damaged pins and connected to a seperate connector that can be fixed to the chassis. Possibly a DB9. Replacing the steppers entirely is a possibility, but will be tricky due to the capstan-drive. Removing the stepper will probably mean re-winding and re-tensioning the system.

The capstan drums seem at risk already however, as the (nylon?) coating on the steel cable is severely deteriorated, cracked and flaking off. Once the coating fails sufficiently to expose the cable, the cable will begin to eat into the surface of the aluminium capstan drums, ruining them. The drums are not likely to be easily replaced, the motors and cable are.

While the cable is fine for testing use, if the Statasys is going to be used frequently, new cable should be sourced as a priority.

The milled parts should arrive any day now and, once installed, we should be ready for a first test print.

As far as I am concerned, based on the investment by members, a successful print of any description, using both extruders or not, is proof of working. Having experimented with Dual Extruders, the configuration too complicated to include this by the (self imposed) deadline.

Currently the Stratasys is moving and the hot-ends/extruders are working. We are waiting for the aluminium to mount the hot-ends in.

Once this is completed, it shouldn't take much longer to have this completed and working.

However, as I mentioned on IRC, if we cannot have a completed print by Christmas, I think this project should be marked as 'not completable' (if there is such as word) and we call it a day...

Thanks Ian

To the mailing list:

Hey all.

Right, finally got time today to do a thorough check-up on the stratasys. As I have rpreviously said, all internal mechanics (including the steppers) are in full working order, especially as I performed a strip and clean to it pre-move.

After a quick talk with Ian on Wednesday, I have traced all the cables and found all the documentation for the parts, ferrous detecting end-stops, x-y controller pin outs, steppers etc. I have removed the old and power hungry heaters and flourescent lights.

I have paird the stepper cables and made ready for the 4-wire board. Also gave another clean

Basically it is ready to be connected to control board and ready to run.

All we need now are to nice tourqey nema17 steppers, 2 j-hotends (ian has offered to source and will start pledge, less than £100). Once these have turned up and I've cad modeled them, i will design a nice clean and easily accesable mount for them in the existing hot end housing (also been cleaned).

Charles will need to add a ACNode and it'll be up and running as a tool for the space. But like the laser cutter and charles, I will be its main care-taker/daddy lol.

Hope this has cleared up any concerns or apprensions about having a fully working, accurate, industrial 3D printer in the space to be used by people with training.

Regards Hipster
