Quotelazzymonk mine isnt soldered. it is just installed in the screw terminal on my ramps board where the fan connects. A 1uf seems to work, but have tried bigger to with success. What kind of capacitor did you use? electrolytic?by boksbox - RAMPS Electronics
Have you tried inserting a 3mm filament or any 3mm diameter object like a drill bit or screw in it?by boksbox - Delta Machines
Try to reduce the DELTA_SEGMENTS_PER_SECOND to 80 or lower in your firmware. See if there's any improvement in stuttering or hiccups. If so, you can hook up your display again.by boksbox - Delta Machines
Quotejmf Quoteboksbox Before you do that, try this - reduce the DELTA_SEGMENTS_PER_SECOND to 80 in your firmware. See if there's any improvement in stuttering or hiccups. boksbox, I did that and it was like night and day, not one stutter since, and I have not had one print failure since I took off the display. Thanks !! I'm using RepRap Full-Discount LCD Display Controller / Arduino Megby boksbox - Delta Machines

Thanks guys. I bought some with about a dozen "blades" inside to bite into the tubing and the collar has some spring action in it. Hope this one lasts.by boksbox - Delta Machines
I mean after slicing in repetier host, you will be brought to the gcode panel. You can check the layers generated by the gcode on screen. See screen shot below:by boksbox - Delta Machines
Do you use slic3r? Check the gcode on the host screen. Turn on travel moves to see non-print moves. Check each layer. If it checks out ok then the problem should be something else, not gcode. Sometimes it can be gcode. I always I check the layers in the simulation before printing and a couple of times I discovered it sliced cavities where there should be just infill.

I've been having this issue with the bowden tube in my extruder. It's loose and the push-fit grip might go at anytime. Note the tape stuck to the bowden tube. Retraction and feeding moves the tube in and out. This is the second time this happened to me. The first time the push-fit wont grip the tube in the end anymore so I had to buy a new push-fit fitting. This time I put a choke on theby boksbox - Delta Machines
QuoteKurzaa Question, how do you know how tight the tension needs to be? There are complex engineering formulas for this but I'm too lazy. My reference is my inkjet printer. I check the tension of the belt driving the printhead. I believe the engineers at Canon and Epson already did the math and any tighter than that would already be too much. I don't tighten my GT2 belts as much but I make suby boksbox - Delta Machines
QuoteStephanel Hey! Good point! Great tip! Didn't change this value too much. Now it also prints much faster. That fast that my Bowden extruder cannot follow anymore, so I had to slow it down :-) Now, there are no issues at the border anymore, and quite frankly, I do not see much difference in the accuracy... Don't slow it down. Adjust E Steps using guide.by boksbox - Delta Machines
QuoteStephanel ( B ) These are the start points per layer but also places where the printer briefly stopped because the RAMPS board could not follow the print speed. This can only be fixed by lowering the print speed or changing to a Duet or similar platform. You don't need to upgrade your electronics yet. I also use RAMPS. At first I had this problem too. In your firmware, try to reduce Dby boksbox - Delta Machines
Quotelokidude I assume you have your belts tensioned correctly? If your belts are too floppy it will cause all sorts of issues. ( I ignored belt tensions on my kossel for a while because I thought if the belts are not skipping that is good enough but then I properly tensioned my loose belts and print quality improved 100%, no more dragging over printed lines etc) I added a set of these to myby boksbox - Delta Machines
QuoteStephanel I tried decreasing the M666 Hxxx value by a few tens of millimeter, but this significantly worsened the print. Try increasing Hxxx value so the nozzle moves closer to the bed. Print one layer of test print with maybe 3 perimeters, no infill. If the first layer perimeter is equal to or thicker than what you set in your slicer, the nozzle is still too high. Increase Hxxx a bitby boksbox - Delta Machines
Quotehercek Rich's firmware is Marlin derived so it probably has ENDSTOPS_ONLY_FOR_HOMING define. Do not define it (comment the line out). Then firmware will not try to move a carriage past an endstop. It will still probably screw up relationship between cartesian and delta ... leading to wrong movements later but at least it will not try to ram past endstops. I tried this and it really messedby boksbox - Delta Machines
Zmax height on deltas can be misleading. Other than 0, you can't have any other X or Y value when it is on Z max. Trying to jog it in X or Y will raise one or two of the carriages past the endstops. And I don't think the Rich Cattell's firmware has a safety feature to prevent the carriage going past the endstops. On other going-past-endstop issue, I'm having random homing problems.

You mean this bracket I made ? -> And I thought you didn't want cross-bracing... Anyway, the cross-bracing definitely stiffens the whole frame. I can grab two of the bracing rods and lift the machine and shake it about without fear of twisting or bending the towers. It adds quite a bit of a bulk to the printer but anything that would reduce vibration will surely improve the performanceby boksbox - Delta Machines
QuoteZedsquared There's always this thing (I've not tried it myself yet) or this: An honor to have my "stabilimod" noticed and shown here.by boksbox - Delta Machines
I found out the trouble. It all started when I changed my endstops to a smaller micro switch (like those used for mouse clickers). They are not accurate at all. I reinstalled the regular SS-5's and things are back to normal.by boksbox - Delta Machines
I've been having trouble getting my bed leveled via auto-level G29 by johann's Marlin both previous and the latest release. Prints are fairly flat but the bed is severely tilted. The error I'm having at points compared to the center near the left front X tower is higher by about 0.1mm (higher) right front Y tower is about the same as the center rear middle Z tower by -0.2mm (lower) I also triby boksbox - Delta Machines
I also posted this problem in a separate topic and with MagoKimbra's help, I was able to make it work. The thread is here> If things don't work out, I will look into your suggestion, aggiehavoc. Thanks!by boksbox - Delta Machines
Well yes. It X min and Y min shows up when I do M119. But where do I put your code? Because on pins.h I see near the bottom these lines: #ifdef DISABLE_MIN_ENDSTOPS #define X_MIN_PIN -1 #define Y_MIN_PIN -1 #define Z_MIN_PIN -1 #endif Should I put them after these? Update: I just commented the Z min pin and uncommented the #define DISABLE_MIN_ENDSTOPS in Configuby boksbox - Delta Machines
I've tried inverting it. Checked via M119 and shows correct logic inverted or not. Z probe works but M29 still probes in mid-air. Reverting to former firmware.by boksbox - Delta Machines
Setting the const bool Z_MIN_ENDSTOP_INVERTING to either true or false still probes in mid-air. I used M119 to check the status of the Z_min in both cases and it shows the correct logic. I noticed however, X_min and Y_min are now also displayed, whereas the old firmware shows only the Z_min. I know the Z probe works because reverting to the old firmware works just fine.by boksbox - Delta Machines
I'm also having trouble with this latest version of Marlin. I can't even make the probe touch the bed. It tries to probe in mid-air. I reverted to the older version.by boksbox - Delta Machines
I think so too. But where to set it?by boksbox - Delta Machines
Has anyone tried the new Marlin update from Johann? It has lots of settings messed up and I had to debug them to work with my Kossel Mini. But I can't make the auto level probe work. I'm using the old mechanical probe type. When I try to run G29, the action appears as if the probe microswitch is permanently triggered. Anyone know what's wrong? I know it's not an electrical problem becauby boksbox - Delta Machines
