Hi all, I managed to re-comission my Mendel reprap, which uses Gen3 electronics and FiveD 20111115 firmware version, but I am having a problem with the print software. So far I could only have a temperature reading by using PrintRun, all other softwares fail to give me anything. From google I understand that this is due to loss of support from the new fimware/softwares. (if true, I would appreciate a confirmation so that I can modify the wiki page of Gen3 for future readers...) Anyway, PrintRun works well to set/read the temperature and to move the axes, but it fails to print any objects. So far I have tried with 3 different files, every time the same fault occured: the steppers are visibly used for about 10-15 sec (the lights flashes) but it looks very random, and then the print finishes. There is no extrusion either. Has anyone experienced a similar issue? Would there be a way around to use another software?

It's working now, just!

I suggest that he/she try out TeaCup, as that is now the most up to date version that still supports Gen3, FiveD is very old.]]> Grogyan Reprappers Mon, 24 Sep 2012 06:14:19 -0400 https://reprap.org/forum/read.php?4,154752,156316#msg-156316 https://reprap.org/forum/read.php?4,154752,156316#msg-156316 For the newer firmwares I have no idea...]]> rhmorrison Reprappers Mon, 24 Sep 2012 02:59:10 -0400 https://reprap.org/forum/read.php?4,154752,156240#msg-156240 https://reprap.org/forum/read.php?4,154752,156240#msg-156240 Grogyan Reprappers Sun, 23 Sep 2012 17:56:19 -0400 https://reprap.org/forum/read.php?4,154752,156171#msg-156171 https://reprap.org/forum/read.php?4,154752,156171#msg-156171
@Grogyan:
I am using the motherboard v1.2 + extruder board indeed, just like you apparently. Do you have any particular problem with the old firmware? Could it be an option to install it back? Why don't you want to use the Gen3+ board?

@Bob:
Do you know by any chance which is the latest version of the firmware that still supports Gen3 without the Gen3+ addon please? I think that the simplest solution for me would be to install it and have an 'old' Mendel for now. Unless there is a catch?]]> Lionel Reprappers Sun, 23 Sep 2012 11:29:59 -0400 https://reprap.org/forum/read.php?4,154752,155826#msg-155826 https://reprap.org/forum/read.php?4,154752,155826#msg-155826 I won't be using that board, as I will use EasyDrivers from sparkfun, switching out the old 1/2 step drivers for 1/8 step drivers]]> Grogyan Reprappers Fri, 21 Sep 2012 15:13:30 -0400 https://reprap.org/forum/read.php?4,154752,155825#msg-155825 https://reprap.org/forum/read.php?4,154752,155825#msg-155825 Also you will need to set in firmware to disable any acceleration.]]> Grogyan Reprappers Fri, 21 Sep 2012 15:05:41 -0400 https://reprap.org/forum/read.php?4,154752,155824#msg-155824 https://reprap.org/forum/read.php?4,154752,155824#msg-155824 rhmorrison Reprappers Fri, 21 Sep 2012 15:03:09 -0400 https://reprap.org/forum/read.php?4,154752,155823#msg-155823 https://reprap.org/forum/read.php?4,154752,155823#msg-155823 Well believe it or not, I am still using my generation 3 electronics, but I hope to ditch the old firmware, in place of Marlin.
From comparing pins, you should just be able to use just the motherboard to control all 4 steppers, and thermal management.
The daughter board mentioned in the previous post will sort out the thermal and extruder connections.]]> Grogyan Reprappers Fri, 21 Sep 2012 15:02:07 -0400 https://reprap.org/forum/read.php?4,154752,155820#msg-155820 https://reprap.org/forum/read.php?4,154752,155820#msg-155820
The Gen 3 has a separate extruder controller that communicates with the mother board over a serial line.
The newer firmwares do NOT SUPPORT this configuration, they assume that the extruder hotend, heated bed and fan are controlled directly with pins on the main board. This is what the adapter does for you, then you no longer need the extruder controller and you can use newer firmwares. This board was designed by Kliment to cure the Gen3 sickness that doesn't allow you to use the newer firmwares.]]> rhmorrison Reprappers Fri, 21 Sep 2012 14:58:29 -0400 https://reprap.org/forum/read.php?4,154752,155807#msg-155807 https://reprap.org/forum/read.php?4,154752,155807#msg-155807 I have seen something similar on a blog, but in my case it doesn't make sense: I can read the temperature using Printrun v32, I can set a point and control the temperature correctly, I can extrude the filamenet and control the potision of the extruder, so I should be able to print an object?
The only thing that seems to be a problem is to control the speed of the extruder, but I need to test this further.]]> Lionel Reprappers Fri, 21 Sep 2012 13:00:32 -0400 https://reprap.org/forum/read.php?4,154752,154858#msg-154858 https://reprap.org/forum/read.php?4,154752,154858#msg-154858 Gen3+ daughter board if you want to use newer firmwares such as Sprinter.]]> rhmorrison Reprappers Mon, 17 Sep 2012 04:04:25 -0400 https://reprap.org/forum/read.php?4,154752,154752#msg-154752 https://reprap.org/forum/read.php?4,154752,154752#msg-154752
