Hello Repraprs I encounter a strange problem with my pursa mendel (1.4), after i just finished to build it and calibrate it i loaded a 10mm cube for testing (using prontface). its took about 30 minutes until its heated the bed (that not the problem) so i tried to pause and reset the printing. After pushing the pause and the restart button the prontface crashed and since then the printer don't response (using prontface). when i upload the sprinter i do see the green light fleshes meaning there is communication. I tried to unplug the power and usb cables and to reload the sprinter, but it didn't help... Any solutions?

1. high current to the motors
2. lot of time for hitting the system up.
not very safety...

Thanks,

i tried to unplug everything, and the com setting are Fine, i also download the Repetier host and indeed its much better program.
when i'm connecting the printer i see this log:

does any one know why the log shows "Unknown command" ? (i read that N2 is related to checksum).]]> coteg Reprappers Sat, 08 Jun 2013 03:00:37 -0400 https://reprap.org/forum/read.php?4,215951,216311#msg-216311 https://reprap.org/forum/read.php?4,215951,216311#msg-216311 sheck626 Reprappers Fri, 07 Jun 2013 12:29:21 -0400 https://reprap.org/forum/read.php?4,215951,216075#msg-216075 https://reprap.org/forum/read.php?4,215951,216075#msg-216075 Maxx Mayhem Reprappers Thu, 06 Jun 2013 18:46:32 -0400 https://reprap.org/forum/read.php?4,215951,215951#msg-215951 https://reprap.org/forum/read.php?4,215951,215951#msg-215951
