**** BEGIN LOGGING AT Thu Nov 21 02:59:57 2019 Nov 21 11:34:35 Hi every bodyI am currently trying to build my 3D printer. For my 3D printer the controller Beagle Bone Black with bebopr ++ Cap was used.Since my 3D printer should work with 2 extruders, I came across a problem and indeed: there are according to my research no suitable firmware, which is suitable for two extruders.I am currently using a firmware Nov 21 11:34:35 (https://github.com/modmaker/BeBoPr) that only works for one extruder and my programming experience is not sufficient to handle the C code of this firmware.if someone gave me a suggestion for a firmware I would be very happy.Thank you very much in advance Nov 21 11:37:56 I forgot to mention that the extension to 5 axes was done with the help of J5Bob (https://github.com/modmaker/J5-BOB) Nov 21 11:40:48 like I said last time, it looks like that project has been abandoned long ago Nov 21 11:43:27 if their firmware doesn't do what you want, you may be out of loud, especially since not all of it is open source Nov 21 11:43:32 *out of luck Nov 21 11:51:19 thanx zmatt Nov 21 11:53:17 have you please any suggestion? Nov 21 11:55:11 should I to change the cap ? Nov 21 11:55:54 What do you think what is the best way to go on in my project Nov 21 11:56:35 I don't have any suggestions, I have no experience with using the beaglebone to control 3d printers Nov 21 11:57:36 oki thanx very much. Nov 21 11:57:41 have a nice day Nov 21 11:57:47 :) Nov 21 11:58:11 zmatt: "out of loud" is an interesting typo. and very, very sad! Nov 21 11:58:32 Robin: rcn mentioned machinekit, have you looked at that? Nov 21 11:58:58 apparently it supports the bebopr (based on what I found by searching the internet for a few seconds) Nov 21 12:09:46 machinekit is like a host software or a firmware ? Nov 21 12:10:03 i would try it thanx thanx :) Nov 21 12:10:06 I have no idea what you mean by that distinction Nov 21 12:11:27 I have thought that the machinkit ist like Slic3r Nov 21 12:11:54 I have no idea what that is either Nov 21 12:14:21 its like a sofware to controll the 3d printer und it makes the G code Nov 21 12:15:59 machinekit is software that would run on the bbb that controls hardware and includes a g-code interpreter, as far as I can tell from these old slides that were the second google hit when I searched for "beaglebone 3d printer" => https://beagleboard.org/static/presentations/makerfaire-jasonkridner-making3dprinters-machinekit.pdf Nov 21 12:19:03 thank u alot i would to read more about it und i would try it Nov 21 13:30:02 m Nov 21 16:08:52 Erro. I'm tring to read the PGDLY value from the PMIC and it doesn't show up as an I2C device at the datasheet's listed slave address. I guess I down to asking what that value is. (pout) Nov 21 16:09:23 Oh. I missed it. Let's see if I can do this after all. Nov 21 16:13:41 i2cget keeps saying 0x24 is busy, implying the system has it locked. Nov 21 16:14:45 -f -y Nov 21 16:15:00 yes of course it's busy, the pmic has a kernel driver Nov 21 16:15:16 Ah. I was loath to -f. Nov 21 16:15:31 it doesn't mean it's "locked" Nov 21 16:15:38 -f is required when there's a kernel driver attached Nov 21 16:15:50 Roit toe. Thanks! Nov 21 16:31:23 Ragnorok: you could also just have looked up its value (0x0C) in the datasheet anyway (there's not really any plausible reason for the kernel to ever change it) Nov 21 16:33:24 actually I guess that clearing LDO1PGM might actually be a good idea now that I think about it Nov 21 16:34:29 zmatt: I know, but I didn't want to assume. (shrug) I've been bitten by that before. Nov 21 16:35:29 if PGDLY were anything other than 0 (i.e. 20ms) then presumably that cap would never have been placed on the reset line and we would never have had the ethernet phy issue Nov 21 16:36:48 but unfortunately the reset defaults cannot be changed (unless you want such a large number of devices that it makes sense to ask TI for a custom-programmed batch) Nov 21 17:01:10 was the famous rant of Linus about ARM board files, involved somehow with the beagleboard? Nov 21 17:02:01 (just for curiosity) Nov 21 17:05:02 dunno, the problem is simply that having to write custom kernel code for every single board out there is complete madness Nov 21 17:49:17 I agree there are always going to be different boards. The kernel just needs to support enough to start and load modules. That was the point of modules so as not to have to rebuild the kernel each time you had a new device, it's the same issue. The number ARM based boards just exacerbated the problem Nov 21 17:50:11 it was just a silly practice. imagine having to have a custom board file for every PC motherboard Nov 22 00:58:12 That is a valid point I suspect that's why someone said "What The Heck" and switched to modular drivers. I remember having to modify the SCSI drivers to support my specific CD-ROM and then rebuild the kernel. Not a pleasant experience. Nov 22 01:38:19 https://lkml.org/lkml/2011/3/17/492 Nov 22 01:39:24 lol, "masturbatory renaming of some random device" Nov 22 01:40:29 that wasn't really TI specific though: "I'm replying to the omap pull request, because that's the one I did last, but I don't know who to "blame"" Nov 22 01:55:01 Has anyone built a heating element burner for cooking fritters w/ the BBB, yet? Nov 22 01:56:27 I mean...it has to have the built in fritter holders that can be scooped up easily and turned over in the fry. Nov 22 01:56:38 Should I? Nov 22 01:57:33 that depends on your fire insurance I guess Nov 22 01:57:46 Ha. I have none. Nov 22 01:58:09 No smoke, no fire. Nov 22 01:59:10 It is better than those stinking metal clips that tell the burner when to lower temp. by way of clicking apart or together. Nov 22 02:02:38 See, the issue w/ fritters are... Nov 22 02:03:03 Once put in oil, they span out. Once they span out, the sweet corn flavor is fried out. Nov 22 02:03:24 Dang it. I think I can. I might try. Nov 22 02:04:20 I saw something recently about burners and electronics. It seemed like I could become a fanactic about it easily. Nov 22 02:05:08 I guess some reverse engineering would suffice until I come up w/ a self-made idea. Nov 22 02:06:20 It might have been 1B that got me interested. Nov 22 02:09:07 KY. Nope. I have to do it here. LA! Baby, baby! Nov 22 02:10:49 https://firstbuild.com/products/precision-bakeware-system/ is something similar but it is oven ready not stove top. Nov 22 02:15:22 I guess like a short fry daddy w/ a cylinder in the middle for mixes/batches of corn meal. That might do it. Nov 22 02:22:37 set Nov 22 02:22:56 the stove top is difficult because of heat stratification and other thermodynamic issues. Nov 22 02:26:51 Aw. Nov 22 02:26:52 Okay. Nov 22 02:26:57 That makes sense. Nov 22 02:32:07 you have the same issue with oil baths too. McD's has a stirer in their oil bath to keep the heat constant in the oil bath for that reason. Nov 22 02:32:19 Oh. Nov 22 02:32:39 See. I would set the temp and make a dip of the meal. Nov 22 02:32:57 you could use forced air as well. Nov 22 02:33:01 Yep. Nov 22 02:33:42 Well, I could quit my lunch ideas if necessary. I just thought that the BBB could be placed in a concealed location. Nov 22 02:34:11 W/ ventilation, a fan, and some protection. Insulation? Nov 22 02:35:07 the controller doesn't have to be in the heat area you know. Often factories have thermocouples strung 50 feet or more from the control system Nov 22 02:35:56 Right... Nov 22 02:35:58 perhaps you should try to define the problem better than figure out the solution. Nov 22 02:36:33 you could be solving the wrong problem. I've done and seen that before. Nov 22 02:36:49 Oh. The issue is not w/ the electronics. It is w/ the way to fry the fritters! Nov 22 02:37:44 I tried to draw up a CAD version of the device. I came close. Some pesky issues arose. I will get back on it soon. Nov 22 02:38:41 For one dude, this is a lot of work. Sheesh. Nov 22 02:51:46 I have to find some heavy silicon that can handle the over boiling heat of oil. Nov 22 02:52:18 Ummm no? the silicon need not be remotely close to the oil. Nov 22 02:53:30 try these guys, they supply McD's a lot of stuff https://www.watlow.com/ Nov 22 02:53:35 Okay. Nov 22 02:54:40 No, get this. Nov 22 02:55:10 An oval, silicon piece that is open on both ends and filled w/ weights on each open end. Nov 22 02:55:31 Got to keep that fritter under control. Nov 22 02:56:04 Cookie cutters for oil? Nov 22 02:57:33 Cast iron maybe...anyway. This is not BBB related. I will shut up now. Nov 22 02:57:59 :D Nov 22 02:59:44 BBB! Nov 22 02:59:57 I mean, this is sort of BBB related b/c of the finished product. **** ENDING LOGGING AT Fri Nov 22 02:59:57 2019
