I have a Makergear Prusa with an Arduno Mega 2560. It was printing fine until I built a wooden housing for it. Now it keeps disconnecting from the PC, some times at a middle of a print. Actually it wont run for more than 1 hour without tilting. Pronterface freezes and I cannot do anything but close the program, unplug the USB connection, plug agin, restart. Any one have an idea what the problem might be? I already tryied the following with no good results 1. Changed the USB cable 2. Moved farther appart the cables transporting 12V form the USB cable 3. Uninstalled Pronterface and reinstalling again I have asked around the Makergear forum but could not get an answer there either I appreciate anyone giving me any ideas Adrian https://reprap.org/forum/read.php?4,143643,143643#msg-143643 Wed, 14 Oct 2026 03:54:47 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,143643,150375#msg-150375 https://reprap.org/forum/read.php?4,143643,150375#msg-150375 Adrian]]> adrianec Reprappers Sat, 25 Aug 2012 10:41:33 -0400 https://reprap.org/forum/read.php?4,143643,144003#msg-144003 https://reprap.org/forum/read.php?4,143643,144003#msg-144003 NelsonRap Reprappers Sun, 22 Jul 2012 04:06:55 -0400 https://reprap.org/forum/read.php?4,143643,143984#msg-143984 https://reprap.org/forum/read.php?4,143643,143984#msg-143984 Zimtower Reprappers Sat, 21 Jul 2012 20:46:07 -0400 https://reprap.org/forum/read.php?4,143643,143929#msg-143929 https://reprap.org/forum/read.php?4,143643,143929#msg-143929 adrianec Reprappers Sat, 21 Jul 2012 14:06:40 -0400 https://reprap.org/forum/read.php?4,143643,143927#msg-143927 https://reprap.org/forum/read.php?4,143643,143927#msg-143927 adrianec Reprappers Sat, 21 Jul 2012 14:05:02 -0400 https://reprap.org/forum/read.php?4,143643,143926#msg-143926 https://reprap.org/forum/read.php?4,143643,143926#msg-143926 Adrian]]> adrianec Reprappers Sat, 21 Jul 2012 13:49:42 -0400 https://reprap.org/forum/read.php?4,143643,143852#msg-143852 https://reprap.org/forum/read.php?4,143643,143852#msg-143852 sam0737 Reprappers Sat, 21 Jul 2012 03:11:52 -0400 https://reprap.org/forum/read.php?4,143643,143706#msg-143706 https://reprap.org/forum/read.php?4,143643,143706#msg-143706
A few things to try.

My guess is that the wooden cabinet may help a potential difference build up between the PC and reprap over time. It gets to a point where it starts causing data transmission problems down the USB cable, which locks up the software / arduino.

Have a look at the earthing of the machine / heated bed and pc and make sure they are earthed to a good common ground etc.

Try altering (usually lowering) your baud rate in firmware and on Pronterface as this may help matters as it makes the data transfer a little more robust.]]> martinprice2004 Reprappers Fri, 20 Jul 2012 07:45:19 -0400 https://reprap.org/forum/read.php?4,143643,143679#msg-143679 https://reprap.org/forum/read.php?4,143643,143679#msg-143679 TomCeeMe Reprappers Fri, 20 Jul 2012 04:50:43 -0400 https://reprap.org/forum/read.php?4,143643,143648#msg-143648 https://reprap.org/forum/read.php?4,143643,143648#msg-143648 akhlut Reprappers Thu, 19 Jul 2012 23:11:13 -0400 https://reprap.org/forum/read.php?4,143643,143643#msg-143643 https://reprap.org/forum/read.php?4,143643,143643#msg-143643
