Re: looking for stubby ball stud - 7 years ago
QuoteMils24 Im pretty sure Haydns are what you are looking for. Go to Thingiverse,search for 'Zero-Backlash Magnetic Ball Joint Rod Ends' and drop Haydn an email. I got the dimensions from Haydn and they are longer than those in the picture that I thought they would fit my setup. However, I checked again and I can make them work, just need to have more care than before. The duet3d and the Ultby shadowphile - Delta Machines
looking for stubby ball stud - 7 years ago
Hi, I can't find the source for these kinds of neck-less ball studs: The stud needs to be M3 and the ball 3/8" (preferred, but I will take 10mm) thanksby shadowphile - Delta Machines
question to DC42 about H parameter in auto-leveling deltas. - 7 years ago
Hi David, you said at one point in the past that the auto-probe results printed to the console of the web interface do not reflect the impact of the H parameter offsets, which means it can report worse than it actually is. If that is true, is there a reason why that can't be different? It's awfully misleading. thanksby shadowphile - Delta Machines
ball-cap rod-end concept pros and cons - 7 years ago
Hello, after custom machining my effector and carriages I am now frequently getting .01 mm auto-levels on a machine with a 300mm print space, which I am pretty happy with. However, the Traxxis rod-ends are definitely the weak link (no pun intended!) and I'm looking at alternatives. The magnetic ball approach seems popular and easy to make accurate but I just don't trust magnets and shudder when Iby shadowphile - Delta Machines
Ultibot direct-drive extruder delta - 7 years ago
I just ran across this model ultibot delta and realized at one point there was no bowden tube. My biggest complaint about deltas are the bowden tubes. The have multiple disavantages and my biggest peeve is unable to use soft filaments. So..how does this machine get away with doing something that opposes the biggest advantage claimed for deltas? (I also read recently that deltas don't have the laby shadowphile - Delta Machines

Re: dc42 version - How to change lateral z-probe speeds? - 7 years ago
We seem to be on different planets Your link goes to the home page for the reprap gcode reference but not to anything specific. I also did not see anything there using a 'T' parameter except Tower Radius in the G30 command. What is the gcode I am supposed to look up? thanksby shadowphile - Duet
Re: dc42 version - How to change lateral z-probe speeds? - 7 years ago
There is nothing in this command about speed and I can't find any other g-code that references this parameter. I inserted 'G1 F10000' before each G30 command but it made no difference. I seem to remember having access to these parameters somewhere (but that might be from my RAMPS days).

Re: Proper way of assembling Traxxs ball ends. - 8 years ago
This is all good to know! I thought just hammering them in was a little brutal but figured that was expected. Some of my rods seem a little loose now, how much printing wear can they take before they start to stretch? I have had a few high-speed (70mm/sec) 10-hour jobs but otherwise my machine sees very low usage.by shadowphile - Delta Machines
Re: why is my H parameter in DC42 branch of Duet not doing anything? - 8 years ago
dougal1957, you are protected by the Good Samaritan law I was not aware that the H parameters would not affect the bed-leveling routine report, that changes a lot for me! With that obstacle removed I can move forward to rebuilding my carriages also as they are a frankenstein of cut-up printed parts, polycarbonate blocks, and wooden shims (blegh!).by shadowphile - Delta Machines
Re: why is my H parameter in DC42 branch of Duet not doing anything? - 8 years ago
Thanks Dougal; I feel like I should have put this in the Duet forum. ; Auto calibration routine for delta printers ; Before running this, you should have set up your zprobe Z offset to suit your build, in the G31 command in config.g. M561 ; clear any bed transform, otherwise homing may be at the wrong height G31 X0 Y0 ; don't want any probe offset for this G28 ; home the printerby shadowphile - Delta Machines
why is my H parameter in DC42 branch of Duet not doing anything? - 8 years ago
I have a 300mm bed and the autoleveling routine was getting around 0.02mm deviation. But my machine warped out at some point and I decided to hell with these printed parts... I built a new effector platform from only machined aluminum parts, and assembled to within .02mm or so in all dimensions. This thing is tight!

Delta jamming at high speeds with large nozzle - 8 years ago
(Note: printer specs at the end) Hi, I have been printing PLA ok with my large-format delta for a while. It has an E3D 3mm extruder and up to now have always used a .4mm nozzle and 'play it safe' speeds of 30 mm/sec. However, I had a high-volume part about 6" by 6" that would take way too long with my usual setup. With some tweaking I was able to print at 70 mm/sec with a .6mm nozzle, although mby shadowphile - Delta Machines

Re: reverse the z-probe trigger logic? - 8 years ago
Quotedc42 If it's connected to the E0 endstop input then you can use M574 E0 S0 or M574 E0 S1 to select the trigger polarity. I can't get this to work. M574 w/o parameters reports E as active high or low wrt to my setting but G30 S-1 always triggers on active high. I have tried this with M558 P1, P2, and P4, and various combinations of M574 E0 or E1 with S0 or S1. I have tried a few of these byby shadowphile - Duet

reverse the z-probe trigger logic? - 8 years ago
I built an opto-interrupted z-probe that goes low when triggered, but I can' find any way to invert the trigger logic. I tried P1 through P4 of the M558 commnad. When I built the circuit I thought I could simply invert the logic to match my hardware. Right now it is tied to the E0 limit switch because I was set up for an IR-probe. Any help? thanksby shadowphile - Duet

I have had this problem for a while. Cycling power of the Duet or restarting the browser do no fix it. The only fix for me seems to be rebooting the PC.

Re: this and that about DC42 firmwares - 8 years ago
Quotedc42 Quoteshadowphile Why are the limit switches even turned off? Leaving them on would at least prevent the sideways crashes at high Z... Checking the limit switches on every step would significantly slow down the step generation. It's on my list to apply soft limits at high Z. I don't understand. Limit switches can drive hardware interrrupts, no overhead at all.by shadowphile - Duet

inconsistent speeds during dc42 autocalibrate - 8 years ago
I have observed that at some points the head moves down fast until close to the bed, then goes slow until triggered. Some other points don't do the fast step, just drift down at the low speed all the way. Slows the auto-cal process somewhat. My config.g parameters have all been tweaked to match the values that were reported after a cal process except rod-length (I use S6) Also, is here any wayby shadowphile - Duet
