all i had to do to finally have a working printer was to upload a new bootloader onto my rambo 1.2d. instead i accidentally plugged the avrisp mkii into the icsp pins connecting to the 32u2 chip for the usb. now my computer wont detect the board and my programmers red led just stays on indicating no target power. does anyone know how to reprogram/fix the 32u2 chip or know anyone i can work around it? i can send whoever helps me fix this some 16MHz oscillators, bag of 50 RGB leds, and an extra mega r3 clone i have. im desperate. ive had this prusa i3 since February and its been problem after problem, i dont give up and at least i've learned a lot though. https://reprap.org/forum/read.php?4,531555,531555#msg-531555 Thu, 12 Mar 2026 09:35:27 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,531555,532446#msg-532446 https://reprap.org/forum/read.php?4,531555,532446#msg-532446 ryan53090 Reprappers Tue, 14 Jul 2015 08:52:24 -0400 https://reprap.org/forum/read.php?4,531555,532284#msg-532284 https://reprap.org/forum/read.php?4,531555,532284#msg-532284 dc42 Reprappers Tue, 14 Jul 2015 01:59:26 -0400 https://reprap.org/forum/read.php?4,531555,532281#msg-532281 https://reprap.org/forum/read.php?4,531555,532281#msg-532281 my avrisp mkii gets no target power when wired to the icsp for the mega2560. but it DOES get the green led for target power to light up when i wire it to the 32u2]]> ryan53090 Reprappers Tue, 14 Jul 2015 01:51:14 -0400 https://reprap.org/forum/read.php?4,531555,531620#msg-531620 https://reprap.org/forum/read.php?4,531555,531620#msg-531620 dc42 Reprappers Sun, 12 Jul 2015 01:59:34 -0400 https://reprap.org/forum/read.php?4,531555,531581#msg-531581 https://reprap.org/forum/read.php?4,531555,531581#msg-531581 ryan53090 Reprappers Sat, 11 Jul 2015 19:57:22 -0400 https://reprap.org/forum/read.php?4,531555,531555#msg-531555 https://reprap.org/forum/read.php?4,531555,531555#msg-531555 ryan53090 Reprappers Sat, 11 Jul 2015 18:12:41 -0400
