Using Cura to Calibrate Your Auto-Leveling Probe - Printrbot Play

NEW USERS: If you ordered an assembled Printrbot, it was already calibrated during testing before shipment.  Unless your nozzle is scraping the bed, try a few test prints before attempting to calibrate the probe.

    How do you MOVE the stuff up, down and so on? It still remains in the top position, dropping from the very high the filament, like a spider. It doesn't lower its position. Is it broken?

    Hi,

    Sorry, there is too little info to help you here: what do you mean by 'the stuff'? Is it the hotend carriage?

    Could you describe what you want to do, what you actually do and what does not work?

    The filament doesn't stick to the floor of the printer.

    I have solved the issue related to the Z axis movement. It didn't move because the metal vertical bar was unscrewed, so the hot end didn't rise. But now that I have tighten that bar the hot end can move up and down.
    Now the problem is that the filament extruded don't adhere on the floor and all I can produce is an inform mass of roasted PLA. Somebody has told me to use G-Code to regulate the height of the hot end of the printer, to be at the right altitude in the right moment, but I don't know nothing about G-code. Can you help me, please?

    Hello again,

    Thanks for adding more precisions. I am glad you solved your Z axis issue.

    If you do not have enough adherence to the print bed, you need to follow the steps above to calibrate the auto-leveling probe so that adhesion is correct. You can find a video of the same instructions on Youtube, just keep in mind it uses the old Repetier and not Cura (but the method is the same). It indeed uses a few G-code instructions to do the job but those are easy (the more difficult part is correctly assessing whether you get enough stickyness, the video helps with that).

    Feedback on the Guide to Getting Started with Cura software

     
    Step 1
    Yea! The URL links work! You need to add Mac details. The Cura software isn’t signed from an Apple Developer ID (can you guys buy Ultimate a beer and give them $99 to get an Apple Developer ID)? I know it goes against their open source mantra, but users are getting tripped up over how to disable Apple’s gatekeeper settings designed to protect users from evil malware.
     
    After launching Cura and getting the message saying the app can’t be launched have the user go to the Apple Icon > System Preferences… >Security & Privacy >General tab and click on the “Allow Cura to open anyways” option.
     
    As of 15.04.3 Cura now has the Makrbot Play settings!
     
    Step 2
    I consider this part of the unboxing steps from their first guide. Why is there no on/off switch? The Play sounds like a JET engine and it doesn’t look like the fan turns off to go to sleep which means I’ll be pulling out the power cord which means I won’t know which adapter behind my desk of cords goes to the Play. Can you add a PB sticker to your power supply? Too confusing without it. Tell users to buy a switched power strip just for the PB to get their ON/OFF switch.
     
    Step 3
    Update the step of select Simple Metal to now say select Play since it is now included in Cura 15.04.3
     
    Step 4
    This can be removed since it is already setup from step 3.
     
    Step 5
    What is a PRONTERFACE?? I googled it and came up with http://www.pronterface.com/ So I went ahead and set it, but it might be good to add a sentence on why they are doing this step.
     
    Step 6
    Does this Play.GettingStarted.ini file need to be saved anywhere specific? I loaded it from my Safari’s download folder. Do I do this step every time or just once? What is this file for?
     
    Step 7
    Next Steps is a bullet point and a separate bullet for click here. Can you merge them?

    Notes for Guide 3

     

    Guide 3

    Using Cura to Set Up Your Auto-Leveling Probe and Create Your First Print for the Printrbot Play
     
    Step 1
    Can you include a photo on what the auto level probe is. Non-obvious for first timers.
     
    Step 2
    Can you include a photo on the Z axis? It took a lot of threading to bring the print head down. I went ahead and put a piece of paper between the blue tape and the nozzle head and kept the z axis just at the point where the paper doesn’t slide smoothly under it.
     
    Step 3
    I’m assuming those of us that bought this preassembled can skip this step. Ok I read through it thinking it didn’t apply to me and learned about that black piece of delrin. Is that the spacing you use instead of the piece of paper like we use on Makerbot and laser printers at the TechShop? I would ship a longer piece in the same color orange as the auto level head so that you can do this without removing the housing.
     
    Step 4
    This is the first time users are loading filament. You should call out the details - use the included bag of 1.75mm PLA filament that came with your printer. Give a link to supported filaments. Tell users how to mount their spool to the spool holder. My HatchBox reel is a very snug fit. Should it unwind over the top? Does it matter if the printer is on or not? Can I freely move the printer head’s X,Y axis around or is there a home position for the head and the plate? 
     
    Step 5
    This is really still part of step 4. 
    There didn’t seem to be any audio on the video example. I would show how to remove the head, cut the filament and then zoom on the upper hole threading, telling them to compress the arm and zoom in on the lower hole and tell them how many mm to thread the filament down. Should the unit be on (preheat?) or off (cold).
     
    Step 6
    This is the first time you mention if power should be on or off. I would add this to step 1 (assuming power off) and then tell users to power on in step 6. 
     
    Step 7
    The click “10” under the z axis was confusing. The 3 screen shots are helpful, but maybe diagram call outs or “click 3 times” with an arrow to the 10 you are referring to. The clicking on Home X and Home Y caused the machine to shake violently. Is this normal? Was this because I had moved the printer bead to put on the tape? Maybe a video link would help newbies through this.
