Have you tried bolting a dremel or router to your RepRap? Can you engrave and drill PCBs? Or cut wood, or ... steel? (Or do you have a commercial mill or CNC router?)
Cooling feature request, fan for perimeters only? - 11 years ago
I would be very appreciative if you could include an option which ran the fan only during the perimeters. I need it for print quality but I also need the piece to stay hot and fuse properly for strength! Thank you, Phizby Phizinza - Slic3r
Re: Marlin, gen7, pronterface, issues - 11 years ago
The printing quality issue I am having is with curves. It gives a jagged edge. From what it looks like and what I read this is because the printer is stopping on every facet end and starting again; this gives the print head time to ooze just a little. I was told that look ahead removes the stops from happening and will therefor prevent the little ooze. I finally managed to get Marlin working andby Phizinza - Firmware - experimental, borrowed, and future
Re: Marlin, gen7, pronterface, issues - 11 years ago
I managed to get Marlin on now. I had to do the standby power mod for the thermistors to my Gen7 electronics and also include in my tables *OVERSPAMPLR after the first set of numbers just how all the other tables have it. For some reason I have to manually start and stop the PSU using M80 and M81. It also does a strange thing where the first 5% of the move is really slow, than it accelerates toby Phizinza - Firmware - experimental, borrowed, and future
Re: Compile and upload with Eclipse? - 11 years ago
Using the Programmer's Notepad that came with WinAVR I managed to upload it using the WinAVR tools that are preinstalled in PN. I had to change the linux path to the USB to the Windows recognised COM4, but it worked after that. Thanks!by Phizinza - Firmware - experimental, borrowed, and future
Re: Marlin, gen7, pronterface, issues - 11 years ago
So I managed to get Cyberwizzard's Teacup uploaded using WinAVR installed with the Programmer's Notepad and using the default WinAVR make and program tools in Programmer's Notepad. I had to change the /etc/ttyUSB0 part in the Makefile to COM4 but other than that it worked. I am however having a problem that now the prints are even worse around corners, the bed seems to be jerking a lot. I haveby Phizinza - Firmware - experimental, borrowed, and future
Has anyone upped the 12v rail on an ATX PSU here? - 11 years ago
I've been reading different ways of increasing voltage on an ATX PSU. One way upped all the voltages together and I thought this may be bad for the 5v line feeding the ATmega. But if I'm only looking at 5 to 10 percent increase maybe it wouldn't be an issue? Any thoughts? The other option looks pretty complicated to me, here is a write up . I'm only looking at getting the 12v rail (which on mby Phizinza - General

Re: Compile and upload with Eclipse? - 11 years ago
Ahh, ok. I also can't figure out how to do the make/makefile thing as I have Windows 7. I'm starting to think I need to install a copy of Linux in a virtual machine to do this firmware stuff!by Phizinza - Firmware - experimental, borrowed, and future

Re: Gen7 20MHz running Marlin firmware? - 11 years ago
I've got marlin compiled and uploaded to the 1.3.1 board, with the 10uH inductor. I have a problem with the thermistors, they read quite low (-23c) when I issue the M80 to start the PSU (still haven't done the insulated thermistor standby by power mod so I have to start the PSU before Marlin lets me do anything due to the safety cuts with temps. But the only thing I can get marlin to do is move tby Phizinza - Next Wave Electronics Working Group
Fan on perimeter only? - 11 years ago
Could I please have the feature to run fan's for the perimeter only on prints? Perhaps even a choice between loops and final perimeter or both? Would help my printing of strong but clean looking ABS parts immensely! Thank you!by Phizinza - Slic3r

Re: Marlin, gen7, pronterface, issues - 11 years ago
That would be even better (easier)... I'm having an issue compiling it in Arduino though I get this: dda_lookahead.c: In function 'dda_join_moves': dda_lookahead.c:219: error: 'for' loop initial declaration used outside C99 mode dda_lookahead.c:461: error: redefinition of 'sreg_save' dda_lookahead.c:219: error: previous definition of 'sreg_save' was here dda_lookahead.c:461: error: redefinitionby Phizinza - Firmware - experimental, borrowed, and future
Re: Marlin, gen7, pronterface, issues - 11 years ago
Errors from Pronterface > "Printer stopped deu to errors. Fix the error and use M999 to restart!. (Temperature is reset. Set it before restarting)" Once M999 is issued > "Error:0 : Extruder switched off. MINTEMP triggered !" So my min temp setting is a problem. I've tried this setting at 0 and -10 and still the same issue. My temp sensors don't measure properly until the PSU is on as thisby Phizinza - Firmware - experimental, borrowed, and future
Marlin, gen7, pronterface, issues - 11 years ago
I have a Prusa with gen7 1.3. It ran Teacup and was working good. I wanted to try Marlin for the look ahead feature so after some messing around i managed to upload it. Pronterface connects but says something about an error and try fixing the error and restarting. Then says something about temperature. (sorry on my phone at the moment, don't remember exact error message). Here's a strange part, oby Phizinza - Firmware - experimental, borrowed, and future
Bridge "attachment" so small, why? - 11 years ago
So I've been printing the 5mm cubes calibration and when it comes to do the bridge my Prusa only starts the bridge what looks like a layer width (0.4mm) from the edge. And finishes the same. If it were to start 2mm back from the edge I feel as though it would "grab" better and stick to the other side better too. Any reason why the bridging only joins on such as small surface edge?by Phizinza - Slic3r

Re: Gen7 20MHz running Marlin firmware? - 11 years ago
Looking in the Marlin firmware config file I'm having trouble figuring out what I need to set and change... First issue is the define temp sensors section. I am to assume temp sensor 0 is the hot end on my gen7 board? The thermistor I used on my heat bed is not in the list. Do I just have to add the table to the thermistortables.h as another number and then choose that number in configurationby Phizinza - Next Wave Electronics Working Group
Getting 0.49v drop across IRFZ44N MOSFET on heatbed... - 11 years ago
So I beefed up the v1.3 boards circuit with solder for both the molex to the source of the mosfet, from the drain to the new screw terminal and from the positive on the molex to the screw terminal. And I am still measuring almost half a volt drop across the source to drain on the mosfet. This means my heatbed struggles to get to 105 degrees. I have been told the IRLB8743 is a better option but Iby Phizinza - Next Wave Electronics Working Group
Re: Run fan only on perimeter possible? - 11 years ago
Polygonhell, so you think that the fan during the perimeter will cool the infill of the previous layer to the point I will still get weak parts?by Phizinza - Reprappers
Run fan only on perimeter possible? - 11 years ago
I have a problem, if I don't run a fan I get the corners curling up on all my layers. If I do run a fan I don't get good adhesion and my parts are weak. Is it possible to only run the fan on perimeters and not loops or infill? If so, what software will g-code this? Thanks!by Phizinza - Reprappers

Gen 7 heat bed connector melted? - 11 years ago
Hi, I have a 1.3.1 gen 7 board. The heatbed lost connection and there was a burning smell from the board. After closer inspection I found the white plug has melted through and the pin isn't making connection anymore.. Is this a known problem or is it the 34 degrees C ambient temperature I am printing in causing heat issues with the board? Suggestions for larger plug or more heat resistant plug?by Phizinza - Next Wave Electronics Working Group
Re: J-Head hot end resistor wiring solder problem...? - 11 years ago
That is a great idea. But I like to keep things with plugs or an easily connectable/disconnectable option. Just so when things go wrong it's easier to pull it all apart! Thanks.by Phizinza - Reprappers
