Re: Ramps 1.4 connecting but unresponsive motors - 9 years ago
Quoteo_lampe That leads me to the idea, you might have wrong EEprom Settings or the Eeprom chip died. You wrote, you've flashed the latest Firmware to be sure, but did you send "M502" and "M500" afterwards to refresh the Eeprom? Also try M503 to see, if anything is wrong with the Eeprom. You my Friend are a lifesaver, resetting the Eeprom with M502 working perfectly! I I hadn't thought of doinby Nova - RAMPS Electronics
Re: Ramps 1.4 connecting but unresponsive motors - 9 years ago
Update: E motor started working again, moves in both direction and at various speed. i still cannot home the other axes therefore the only command i can issue is a move UP, when i do that the printer move DOWN and crashes into the plate, since we are talking of a delta this means XYZ stepper and motor works fine. I am now thinking that the problem lies in the mega2560 since it appears as a bad loby Nova - RAMPS Electronics
Re: Ramps 1.4 connecting but unresponsive motors - 9 years ago
Quoteo_lampe Did you check your endstops? Might be a stuck switch that keeps the motors from moving? You could also check the voltage between Vmot/GND pins on the driver chips. All endstops work fine (3 endstops and the probe), I'm going to check if the driver chips get any current asap!by Nova - RAMPS Electronics
[SOLVED]Ramps 1.4 connecting but unresponsive motors - 9 years ago
As i wrote in the subject my ramps 1.4 is behaving strangely after a power on/off/on, i should mention that the printer worked totally fine, i just did a 20 hour print and some minor prints in the last days. The board connect fine with the PC, i get the normal reads at the boot, i can load eproom value, the extruder/bed thermistors read the temperature and i can heat up both, i can power up the fby Nova - RAMPS Electronics

QuoteMutley3D Krizzap, Check this out for a Kossel Mini Now a completed design. The rest of the album can be seen here The finished part looks good, very compact (only the idler is a bit of a mistery), is great that you're making progress with the Delta compatibility. It seems that right now there is no space for a probe but i'm sure that once the design will be available we'll be able to fiby Nova - General

Quotepaul18 Hi Maybe you can have a look to the following link and more precisely the pdf file if you're a math fan Paul That seems rly interesting, even if it's gonna take some time to actually study it Thank youby Nova - Delta Machines
Re: Custom Delta Size/Arms Advice - 11 years ago
Quote3DRapidClone The 80% rule is not really great to use. Its a rule of thumb. You want to know exactly how large you can print. Do some trig and calculate the minum angle to be 20 degrees. Add in your effector offset and you'll get something much closer to reality Ok so, let me understand correctly, you're saying that the arms should be long enough so this ( ) angle it's never less then 20° wby Nova - Delta Machines
Re: Custom Delta Size/Arms Advice - 11 years ago
Quotesungod3k I think your calculation is mostly right, Im sourcing arms as well now and the rules I follow are "side lenthg * 80% = arm length" (the google doc I think uses the same rule) and "angle of base to arm in maximum position should be bigger than 20°" I will by my arms from trid printing and then have 4-5 sizes there you could check for which machines they sell arms and how the dimensioby Nova - Delta Machines
Custom Delta Size/Arms Advice - 11 years ago
Over a year ago i builded my first 3DPrinter (a prusa i3 boxed), the information from this forum were incredibly helpful , now i'm thinking about building a delta and again I find myself in need of some advice, hope you guys can clarify something for me! I've all the information i need about the electronics, hotend, structure part, my "only" doubt is about the ratio between the base triangle sby Nova - Delta Machines
Re: E Motor Problem - 12 years ago
Quoteuncle_bob One very likely issue - the little crimp on pins in the connector got crimped over insulation on the wire. And now it works, amazing ^^ I've unwrapped the cable and straightened them, checked the connector and changed the cable routing, and it just started working again! I'll check component by component tomorrow to understand which one failed in the first place, right now i canby Nova - Reprappers
Re: E Motor Problem - 12 years ago
Quoteuncle_bob Have you checked the wires on the connector going from the motor to the board? mmm, not rly since all the cable have spiral wrap on them.. Well, i'll unwrap them and check when i get home from the universityby Nova - Reprappers
E Motor Problem - 12 years ago
Hi again, last time i posted here i was asking for advice about my first RepRap, i ended up building myself a Prusa i3 Boxed =) The printer is just great, i finished it 2-3 week ago and i've tuned it day by day, in the end the printing result were realy, realy great. Now suddendly the E motor has decided to behave strangely, the problem showed up yesterday and i cant find a fix for it, i've searby Nova - Reprappers

Re: First Build, some doubt (Prusa i3) - 12 years ago
Thanks for the advice, i would use the original parts but i dont like that in that piece the extruder is holded by a bottom plate, however, I will consider your advice =) Regarding the fans, i have seen all king of setup and im still a bit puzzled, in an average situation printing PLA i'll need a fan pointed on the upper part of the extruder (the red part) right? just to help cool it down, and iby Nova - Reprappers
First Build, some doubt (Prusa i3) - 12 years ago
Hey, i'm almost done with the list of components for my first RepRap but i've some doubt, mainly with the extruder and his support. I'm thinking of builing a Prusa i3 Boxed using this printed parts (), but i was thinking of using this () x-axis carriage insted of the standard/old one (the one that can be found on the page with all the other printed parts). For the extruder i was thinking of thisby Nova - Reprappers
