    Dimension soluble support problem

    Please take a look at: http://imgur.com/a/NYWTU

    This is regarding the brown P400-SR soluble support for Dimension sst models. Extrusion appears to be working fine, temp is set to 270c, no errors. Initial raft for pretty much any part comes out perfect, but after that any support is hit and miss. Sometimes I get somewhat acceptable results, but most times with any decent amount of support structure generation, it fails and becomes a tangled mess of soluble support all over the build tray. Any idea of what may be causing this? I have tried SMART, surround, box, etc. (basically all the options of support types). Thank you for your help!

    Run the tip depth calibration and post a close up of that. Suspecting that maybe the model side is a bit out of spec and its causing clogs when you have parts passing over support.

    Ok the_sharpp, you are good!! . I just ran the 'test_tipdp_plstc' maintenance part and the back left and right were blobs of unreadable blobs, the front left basically had nothing and the front right all I could see was faint 55 with a line under it. I would post a pic but it is useless. Actually I will still post... hold pls... Ok not great pics but I hope they are helpful..if not please let me know!

    And here is 'test_tiplevel.pc' maintenance part:

    Can you give me an guidance on how I should proceed? Thank you very much for pointing this out, , I appear to have a miscalibration?? -J

    Would the safe/first thing to try when calibration is out of whack (apparently at a minimum the z axis?) be to load up MaracaEX and get the original calibration CD from inside back panel and load those original calibration files? I can't imagine the original loaded calibration values have changed, and not real sure how to compare what is loaded now against the CD values.

    Maybe this is going about things the wrong way?? Thank you! -j

    Right now, if im understanding you correctly, something is mechanically wrong. You are gouging in the back of the tray but barely hitting it in the front.

    Try this: Grab the front of the z stage platen (where the locking tabs are) and lift it up slightly. if you can tilt the platen and support arms up and down in reference to the guide rods..... Your bearings in the z stage are hosed. Also a good time to check to make sure the guide rods are secure.

    If that all seems fine, let me know and we can check on something else after that.

    Do this for me too:

    On the back of the swivel head you still see a black bar. when you toggle that back and forth you will see what looks like a Philips head screwdriver bit with a flat tip drop down. Take a picture of that for me. If it looks like a rat chewed on it then it could be causing improper Z calibrations.

    It is actually the front where I would say where it was 'gouging' and the back where it wasn't touching very well when doing the 'test_tipdp_plstc'. Just backwards of what you said above...

    I really appreciate your help with this, I have read in the past about z-stage bearing issues with others and was hopeful I wouldn't ever encounter this. Maybe it is my turn..., when I lift the z stage from the front (by the front tabs), my guess is it moves about a 1/32" up/down. There is a noticable movement with respect to feeling the slight move with my fingers and a slight metal to metal click feeling. I imagine that must mean my bearings are gone, correct? This is sounding like a huge problem. Let me also add, this printer has very little hours on it. Total prints is under 50, long story on why that is but I was the happy recipient of obtaining it.

    EDIT: After inspecting more closely, I don't think the bearings are shot. I can push firmly towards the rear with hand against the vertical smooth rods (one on each side of the z axis lead screw) and the bearing slop goes away. It feels like there is slight movement in the z axis smooth rods. Not sure if this is common, and haven't figured out how to tighten them (if even possible). So when you mentioned checking to see if the 'guide rods' were secure, I am betting those are what you were referring to? Hopefully this will be a bit easier to get back into calibration...

    EDIT 2: I tried the 'test_tipoffset' maintenance test part and here are the results of that test:

    And 'test_tipdp_foam':

    I am fairly certain the toggle head has the springs inside and the bar that slides back and forth to toggle between the materials, mine isn't like that. Mine has two motors inside, not sure what they call it and not even sure if it is newer than toggle head or older. This is a 768Sst model, not the 1200sst model. I believe it is a later generation version as well, the serial number is P09XXX, picture here: https://ibb.co/hwAa7Q

    I wanted to add something that might or might not be helpful. When printing a part with default 'SMART' support, I originally showed this picture of my result: https://ibb.co/ntddSQ

    After changing the SMART support settings to add 'use model material where possible', I got a bit better result with the part. This is how it came out: https://ibb.co/kaScMk

    Just wanted to show what I have tried. Thanks again! -j

    The swivel heads still has a toggle bar in the back to drop the z substraight detection plunger. here is the image of were its located. https://imgur.com/a/vX6W5

    When you toggle it back and forth you will see the tip drop down. mine is a grey color but yours might be black. Check to make sure that looks good.
