Re: Homemade Delta, printing problem, need professional advice - 9 years ago

Quotevreihen @jmf - My response was to them in response to them asking for someone else's Repetier EEPROM settings, *not* a criticism of anything you posted..... No problems, I'm a noob at this stuff and am always learning from you guys. I see your awesome replies and how you're helping others a lot with your knowledge, that's really cool and much appreciated !

Re: Homemade Delta, printing problem, need professional advice - 9 years ago

I only gave my firmware files as reference, to possibly find some obvious mistake, that's all, I know it's pointless otherwise....thanks.

Re: Homemade Delta, printing problem, need professional advice - 9 years ago

From the pictures I see no obvious problems, are the towers perpendicular and 90 degrees to the build surface, are they spaced evenly from each other at 120 degrees, what firmware are you using. Double check all the delta offsets. I've attached my configuration.h and configuration_adv.h files in case you are using Marlin firmware, this is my setup for my delta which works perfectly.

2 to 1 Belt Driven Bowden Extruder's for sale.. - 9 years ago

Hi all, I've been needing a good bowden extruder for my delta and was unable to find one I liked, so I made my own 2 to 1 ratio belt driven extruder for 1.75mm filament. This extruder is basically some ideas from others out there with some modifications that I added. The extruder comes with a Nema 17 KL17H248-15-4A stepper, 76 oz-in, and a built in 40mm cooling fan. After many adjustments and

Re: Is it gcode or hardware ?? - 9 years ago

Quotebigfilsing Hi all Just building a mini kossel now. Does this happen with all LCD attachments to ramps or is it just the full graphics version ?? Thanks I'm not sure on that one either, anyone else know ?

Re: Is it gcode or hardware ?? - 9 years ago

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 !!

Re: Which printer type ? - 9 years ago

Good link, that will keep me busy for a while, the more I'm checking into the CoreXY the more I want to build it.

Zavashier, thanks for the link.. Ohmarinus, the CoreXY system looks like the one for me, I love fun, fun, fun....LOL !

Re: Which printer type ? - 9 years ago

Both designs look like fun to build and both look like they may have some advantages or disadvantages, I think I'm gonna try the CoreXY though, that one does look really cool.

Re: Loose Bowden Tube - 9 years ago

Quotetriplanedave Agree with JMF here. I have some push-fits that have only 3 or 4 clamping "blades" in them that hold the PTFE tubing in place. The blades seem to break easily if the push-fit quality is questionable. Honestly, unless you're getting a good quality push-fit, consider these things consumables. Buy a few extra. I can't speak to the ones with the Ebay link, but they look like th

Re: Which printer type ? - 9 years ago

Thanks for the suggestions, I'll have to do some research on this printer, some of the designs look really cool. Why is it called CoreXY, just curious ?

Which printer type ? - 9 years ago

I finally have my Delta printer up and running smoothly, I have a lot of extra parts and now I want to build another non-delta printer. What is a popular printer out there, what type would be a good next printer project ? Thanks, John

Thank you Dougal1957, this was driving me nuts, I will start reading up on the smoothie board and change it over. UPDATE: Yeeeha, that was it ! I just finished a 4 hour print without one hiccup, thanks again Dougal1957

Re: Is it gcode or hardware ?? - 9 years ago

Quotedougal1957 There's your answer it is a fairly well known fact that adding a full graphics controller onto 8 bit control boards when coupled with a delta causes drop out. The Mega 2560 based boards can't cope with the extra processing that is required. Doug WOW, that's exactly what seems to be happening. I'm disconnecting right now and change the firmware file to disable it. I never knew

Quotedougal1957 Quotejmf Here's a new one, I was printing this morning, all was well then it printed almost an entire layer at like zero speed, it was moving but barely, then it started printing normally again ??? Do you by any chance have a full graphics LCD Display fitted and I am assuming here that you are using a Ramps setup? Doug Yes, I am using the full graphics with a Rambo board.

boksbox - thanks, I understand, yes I have been checking it with Repetier. vreihen - Yes, I am using belts and pulleys and they do seem a bit tight, I'm new to this but how would tight belts affect the print, I have not tuned my steppers, not sure how to do that ? Thanks John

Is it gcode or hardware ?? - 9 years ago

Lately it seems like I have more print failures due to the printer making some kind of strange move, like burying the head into the material, raising the head and continues to print, sometimes it just goes out in one direction for no reason then returns to the print and continues to print. This is starting to bug me, I have no idea why this is happening, is it bad gcode, or something wrong with

Re: Is it just me ? - 10 years ago

dc42 - That's what I'm beginning to think, I'm checking config right now. I'm using a temp gun on the hot end and it's not even close to what I'm thinking it should be, are temp guns an accurate way of reading the hot end temps? I increased to 220c and it seems much better, I'll keep experimenting a bit, the extruder wasn't working as hard either.

Re: Is it just me ? - 10 years ago

Quotevreihen I think that it's just you. Everyone else's printers here went together without a hitch, and mine didn't even need calibration! Seriously though, we all get frustrated at times, and most of us probably have a pile of printer parts that didn't work out for one reason or another. Take a step back, take a break, and look at every problem with a fresh perspective as they pop up.....
