    I have had my 1403 since the middle of February. There does not look like there was a firmware update after that. I did the install and my bed heats up but my hot end does not. I am new at this, but I have not had any trouble up until now. help!

    Hi Teodoro,

    Perhaps some of the hotend's wiring was bumped while installing the bed.  Inspect the circuit board area to make sure the hotend power and thermistor connector are fully seated.  Also inspect the hotend are where those power and thermistor connectors plug into the hotend itself.

    Thanks for the response. Everything appears to be connected correctly. I deleted and installed cura again just in case. I did not turn on the headed bed feature so that I can test the print ability. It fires up goes to print and only checks the bed level in one place and then goes directly to print. The problem is that it does not go up on the z axis. It prints at only one level. Of course I cancelled the print and used cura to move the z axis up and down to verify it functions and it does. Any help would be appreciated.

    Hi Teodoro, if the print begins, I assume that the hot end is now coming to temp.  The print would not start otherwise.  If the Z axis is not raising during the print, check the set screws on your Z axis coupler.  If they are loose, the motor shaft may be spinning inside of the coupler.

    Dave,

    Thanks, but this is not the problem. I have now updated the firmware twice and added the G29 to the start-gcode so that it will check the bed level. Who knows where G29 went as it was working properly for over a month and several prints.

    Like I said before I can use the UI to move the Z up and down. I did another test print and carefully watched the Z Acme screw. It did not move at all and printed all on one level. 

    since updating the gcode I have not tried to plug in the heated bed or change the wiring again so in theory it is in the shipped configuration. 

    Is this a board issue? Can I just send the board back for repair? This seems to be a software problem as the Z does manually function.

    To add:

    This is a refurbished Simple Metal. There is also a new development. When I unplug the USB from the computer it no longer makes that "windows" sound when unplugged or plugged. Although it will attempt to print when plugged in it no longer makes that sound. The sound does work on all other items plugged or unplugged from the computer. 

    Hot end issue: I have not tried to set up the heated bed again and the hot end works fine as long as I do not install or set up the heated bed. With the heated bed installed the hot end does not heat up, but only the heated bed. Of course since the hot end does not heat up, it never goes to print. 

    Everything worked before trying to install the x upgrade. I truly regret ordering the upgrade. This is my only printer and I use it for my small business. I have a serious project that I need to get done and I am held hostage with very slow communication (Ironic in this day and age) and a Printrbot that does not work. 

    I had asked in a formal request to just be able to talk with someone and that has not happened and is the same as communicating in this forum. Slow. It is clear that people may not be reading my post completely as I have explained several times that the Z functions with the manual controls in Cura (electronic controls) but does not work during a print. 

    Is there any way to just get a new board set up for a heated bed x upgrade?

    Please help.

    Teodoro, I'm sorry if you unhappy with the communication from our support team.  From looking at your ticket and this forum thread, I see that you have been in contact with literally every support staff member that we have over the course of this past week.  Be aware, weekends are "off hours" and responses can be delayed in those times.

    "Like I said before I can use the UI to move the Z up and down. I did another test print and carefully watched the Z Acme screw. It did not move at all and printed all on one level. since updating the gcode I have not tried to plug in the heated bed or change the wiring again so, in theory, it is in the shipped configuration. Is this a board issue?"

    • It is possible that some metal-on-metal contact has caused an issue with the board, but it is not certain at this point.  I see that you are able to connect and send manual commands to the Z axis.  Are you able to issue all other commands successfully through the Pronterface UI? - advance/home X and Y axis ...bring hot end to temp ...extrude ~5mm at a time.  If all of these commands are successful, it is probably not an issue with the board.

     

    "Can I just send the board back for repair? This seems to be a software problem as the Z does manually function." 

    • We do not offer a repair service for the boards specifically.  We do offer a service called the Bot Spa Treatment if you would like our techs to diagnose this.  Since you are on a time-crunch, I am not sure this is the best option for you.  However, if you are unable to track the problem down, it is an option.
    • To clarify, Printrbot is a hardware company - not a software company.  So, I can't speak directly to the functionality of Cura.  That said, if you are able to successfully able to issue all manual commands, we can be confident that everything mechanical is good.  Also, the software is likely in order if it is issuing the commands to the printer.  It could be a setting in the software or an issue with gcode.

     

    "Hot end issue: I have not tried to set up the heated bed again and the hot end works fine as long as I do not install or set up the heated bed.

Of course, since the hot end does not heat up, it never goes to print.   Everything worked before trying to install the x upgrade."

    • I agree that installing the upgrade seems to be the catalyst for your issues.  My advice for the short term would be to unplug and remove the heat plate so that you can move forward with your project.  If you are able to print an entire project without issue, we can start to isolate that the problem lies with the heat plate.
    • If the Z axis issue continues without the heat plate, I would again be suspicious of gcode.  To test that, I would recommend running a previously successful gcode and monitoring the printer.  Give this test cube gcode a try to monitor mechanical movement.
