Re: Hacked Ender-2 SD card problems - 7 years ago

Forget the file above, it is not working for me anymore as it was somehow. Tried a lot of stuff after searching the Github for open and closed related issues, but no success. I have raised two issues on the Marlin Firmware Github concerning the initialization of the SD card itself (when a custom bootscreen is used) and the incorrect displaying of the SD card menu's.

Re: Hacked Ender-2 SD card problems - 7 years ago

I believe I have solved most of the issues. The 'Print from SD' menu is functioning for printing and displays correct now. The 'Change SD card', ' Init. SD card' and 'Refresh' options do create a dark bar, but they go away when you scroll. If you would like to test, replace the 'ultralcd.cpp' file in the Marlin directory with the one I have attached and recompile/upload. Let me know if this work

Re: Hacked Ender-2 SD card problems - 7 years ago

Thanks for the update. I have been playing around with Marlin options like: - SPI_SPEED - lcd delays - font sizes A big problem is the small memory size of the used 1284p chip, some Marlin options use a lot of memory and you must comment out other options to try different setting most of the time. From within Repetier-Host or Pronterface I can manage the SD card, adding or deleting files works

Re: Hacked Ender-2 SD card problems - 7 years ago

I can confirm the issue with the SD card and screen. I am working on a custom Marlin for the Ender-2 when I found this out. Too bad I did not search here beforehand. Also a custom _bootscreen.h is all garbled up. Trying to use slower spi speeds for SD reader in firmware gave no solution. Wiki for this lcd type is not very helpful either... Any of you found a solution in the meantime?

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

I have printed the parts I have changed but still need to exchange them on the printer. The nice summer weather we currently endure has somehow slowed down the progress. The current *dev* version found on Onshape will not change any further for now, the measurements are spot on to assure a correct belt path.

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Like the way you found an all-in-one solution for the normal ALU version! Maybe I will try and see if I can find a neat way to add the front tension adjustment part to my version as well. Did you also mention your design in the original Smartfriendz SmartrapCore ALU thread?

Re: Octoprint problems - 8 years ago

Nice! My initial experiences with the first generation RPI were simular. That's why it was the first thing I thought of, reading your post.

Re: Octoprint problems - 8 years ago

I use the same Pi generation as you and do not have had that issue, ever. Did you also try another power supply, as the Pi's prefer a very stable one being used?

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

I was talking about the front double pulleys you suggested. When using them and thus bringing the belt path wider (and not using the motor pulley directly), you have the possibility of moving the y slider pulleys more to the outside as well and thus having longer X rods.

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

I have been playing with that idea as well and already incorporated the double supported design for the set in the back, as you can see in the screenshots above. By off-setting the bottom and top idlers, the belts do run parrallel and perpendicular where needed. The belts cross each other in the back this way. As said in a previous post, I got that idea from PDBeal who added that to your double

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Thanks for your interest. I made myself a promise to finish it, I started after all. About the Z axis, so much advice and opinions... Just read all and take note about the best practicesand use from it what is best for your situation. I also want to try different versions and techniques. Kind of learning while doing. Making mistakes is part of the experience. Taking an existing design and

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

That was also my thinking, by adapting the original Smartfriendz version to my needs. :-) For the z axis I did already design a dual version using two leadscrews and two motors (also not ideal). This was not updated here and on Thingiverse. Currently I am working on parts which make the belts run perpendicular, but this will come at the cost of almost 50mm less build volume in the X-axis.

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Hi Ikcl, thank you for your extensive explanation regarding the issues with the alterattions I made to the SmartrapCore design in my version. Much appreciated! And of course Wurstnase for addressing the matter. I had totally forgotten about his thread, have not been printing and designing for a while (follow topic and mail notifications were off). On Thingiverse, I have updated the description

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

New parts available for Endstops X and Y. I have found a simple way to use Optical Endstops and a couple of pieces of a tiewrap to trigger them. - part YSlide_Bot_Endstop has been changed to include a slot for a piece of tiewrap to be mounted - new part YSlide_Bot_X_Endstop_tiewrap has been added which replaces the YSlide_Top_Bot part, which also has a slot for a piece of tiewrap. - new part Y_

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Hi arieljn, thanks for the kind words. The updated parts also have a closed Z_Bottom part, althought the photo's above do not show that clearly. The first version was not closed, as I was going to use a bottom mdf plate. Later decided to close it around the back to the underside of the alu tube. Currently I am preparing and cleaining up the Onshape design for release and will add a new design

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Hi Niels, Seems like a nice solution you came up with. Love the reuse of the old Dutch Reprap (even if it is a lookalike)! How are the NEMA11's holding up, what kind of speeds can you print at? Looks like a nice project to make a nice small desktop printer based on CoreXY. When you can invest some time in Onshape, it will be a much better tool for designing for 3D printing then Sketchup.

Re: SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Thanks Mike! The comment you made catalyzed my thinkingproces completely! While I was solving the X axis width problem, I had to make changes to the belt path to make that happen. Also, the initial tube corners I used did not offer the sturdiness for the top I hoped for, even with the braces already in use for the bottom part of the frame. As you did not answer my reply on Thingivers, I had to

SmartrapCore HK13 (8mm rods - 13mm square Alu tubes) - 8 years ago

Some of you may already have seen my 8mm rod parts for the SmartrapCore standard version (thingiverse). I have been adapting more parts to suit my needs for the experimental version I have designed. Since Smartfriendz released their ALU version and upgraded standard version to Onshape, I have been playing with them while learning Onshape. The experimental part of this is to see if a design with

Re: Fan duct for kossel mini - 8 years ago

No pun taken (and given), I must have misread your remarks. In the meantime, I have ordered some squirrel cage fans (4020 size, 24V) and when time permits I will start working on a design that will incorporate both these fans and a top mounted hotend as well Let us see what we can come up with!

Re: Fan duct for kossel mini - 8 years ago

@ DragoslaV, You are right... For the design you suggested. Now look a second time at 'my design' and read my remarks again. ;-) Today I found out that Haydn Huntley is working on a design for a delta effector (using magnetic joints) using the squirrel case fans which looks very promissing: All we need to do then is adapt it for a 40mm effector for traxxas mounted rods.

Re: Fan duct for kossel mini - 8 years ago

@ DragoslaV, Like I see the design Olaf linked, it is designed the opposite of what you describe? When connecting the two down blowing fans to the D9 connection, you can control them. On for PLA after first layer or completely off for ABS. Whatever you want, need or like. Off course supply an always on supply of 12V or 24VV straight from the power supply for the heatsink cooler. @ nebbian,

Re: SmartCore ALU - 8 years ago

Mike, I am at work currently and do not have them at hand. When you search in Onshape on my user name or smartfriendz, you should be able to find my copy. It is public as well. The files that I have changed are last, ending with _8mm and _8mm_HK13.

Re: Fan duct for kossel mini - 9 years ago

Both your thoughts and alternatives are appreciated, DragoslaV and Olaf. I like those designs as well, although they are not suited for my needs. Seperate and sufficient cooling of both the heatsink and the printed part cooling mostly for PLA. Controlled (can be turned of) part cooling from both sides of the hotend nozzle was on the wishlist as well. The second design Olaf linked does not have

Re: Fan duct for kossel mini - 9 years ago

Thanks David. Although originally not completely my design, I have put in a lot of time redesigning it. The original I found did not fit on an E3Dv6 at all and the guy who posted it never replied on my questions concerning this. I also requested the source files to adapt it for my need, but nothing on that either. There was only a .stl file to begin with. As I do own a Pro version of Sketchup (

Re: Fan duct for kossel mini - 9 years ago

Hi Capinho, if I may be so blunt to promote my (re)design of a more compact solution for a combined hotend fan and printed part cooling thingie? I recently finished my version for the original E3D6 hotend and started using it a week ago myself. I just uploaded it to thingiverse for others to print and use: http://www.thingiverse.com/thing:1005917 I hope you like it!
