Re: Comparisons - what speeds do you get? - 10 years ago
QuoteMrDoctorDIV I used to have an acceleration of 1000m/s2, but have since raised to 4000m/s2 and a bit slower speed, vastly improving my quality. Ah, but the question here is - was it lowering the speed or raising the acceleration that made the improvement?? The jump from 1000m/s2 to 4000m/s2 will make the overall print speed more 'linear' (for lack of a better term) which I could see helpingby Switchblade88 - General
Re: Help! (X,Y & Z carriages) - 10 years ago
Hi Master_Wither, welcome to the forums! It might be worth flicking through the original designs on the wiki to see how RepRaps have evolved. The original 'Darwin' had a moving X/Y carriage above a lowering Z-bed. That gave way to the Mendel with the X-Z carriage above the Y-axis bed, same with the Prusa i3 (what I've got). Axial movement is a negligible effect on quality of prints, compared toby Switchblade88 - General
Re: Comparisons - what speeds do you get? - 10 years ago
QuoteTraumflug Can we assume you mean 500 mm/s2, 9000 mm/s2 and 100 mm/s? Indeed, just edited to correct. I don't know about other firmwares, but Marlin's default is excessively high for any RepRap design; unfortunately I didn't realise that until further researching and traced it down as the cause of my missed steps. Upon fixing that, I could significantly push my speeds higher with less risby Switchblade88 - General
Comparisons - what speeds do you get? - 10 years ago
Hey all, I'm just curious as to the communities' general consensus on 'reasonable' speeds are for an 'average' RepRap. I know, I know, there are so many variables in play here - I'll narrow them down to my scenario, and tell me how yours compares! - Prusa i3, Alu frame, direct drive extruder - Printing PLA onto PVA juiced glass, non-heated - Acceleration at 500 m/s2 (much smoother now it's loweby Switchblade88 - General
Re: Smooth rod sources in AUS - 10 years ago
It's pretty hard! I'm going to grab the Prusa i3 frame kit from 3DJunction which comes with all the metal vitamins. If I tried to source all these parts separately (even just the bolts, rods and washers etc in bulk, and the frame) then I think I'd still be worse off, even without the smooth rod set. In saying that, I contacted Interlloy and they gave me a rough cost of $10 for 2kg ($5 per kg?)by Switchblade88 - Australia, Melbourne RUG
Re: J-head with ceramic body instead of PEEK - 10 years ago
I've always wondered, since seeing someone's post about using sodium silicate to patch their hotend, whether it would be usable as a structural component to directly mount the brass into. You can get an exhaust patch kit (like this one ) for $10aus and it appears to have enough strength to handle strenuous loads without issue. Any feedback on this - or previous experiments along these lines?by Switchblade88 - General
Smooth rod sources in AUS - 10 years ago
G'day all, I'm trying to chase up local sources of 8mm smooth rod here in Aus... as a first-time pending builder I'm not confident as to what I'm looking for or the grade to price ratio of rods. Can someone help with details and suppliers? I know clarky on here has the full set for about $60 but I was happy with cheap rod at $30 or less to get my toe in the water first... Thanks guys!by Switchblade88 - Australia, Melbourne RUG
