Re: HE3D Delta -600 build review - 8 years ago
..... the MDF plate at the bottom of the heat bed is original..... There are certainly easier ways to build a printer, and knowing what I know now I would just build it from scratch, but I think it was a valuable learning process trough which I was able to source a lot of great suppliers of the key parts, its easy to look at the finished thing and identify that there is nothing left of the kit,by bgkdavis - Delta Machines

Re: HE3D Delta -600 build review - 8 years ago
Well the good news, is this is now by far my best, fastest, quietest and most accurate printer (I have three) and it prints extremely well with both PLA and ABS The bad news..... there isn't much left of the original kit - aluminium extrusion - motors - sprockets - belts - some bed components - power supply - axis limit switches - bowden tube - power switch - a fan (maybe) - some wires - mountinby bgkdavis - Delta Machines
Re: Bad bearings or bend rods? - 8 years ago
have you a pair of calipers to measure the distance between rods and bearings? if no the try swapping moving the carriages between the good rail to the bad rail if the problem stays on the same rail then you have a rail problem, if it moves with the carriage then you have a carriage problem from your vid I would guess there is a problem with the carriage, you may find the printed body is slightby bgkdavis - Fisher
Re: First layer improvements? [pic] - 8 years ago
You need to set the H parameters for the calibration probe positions, each position will have a different H value and they need setting individually.by bgkdavis - Fisher
Re: IR sensor ??? - 8 years ago
the first things to check are the led on the sensor board and the feedback value from the sensor. When you power on the machine you should see a rede led on the sensor board flash 3 times,if not makre sure you have the board correctly plugged in and the wiring to the duet is good. If this is good next look at the modulated value on the web interface, use a piece of white paper do you see the vaby bgkdavis - Duet

yeah upside down I guess it is then Fortunately I can see where the heated tracks are through the silicon, so whilst its really not to be recommended I reckon I can put some holes through at the very edgeby bgkdavis - Delta Machines
Re: Upgrading heat bed - 8 years ago
Well Ive finally got a silicone 240V bed from these guys , getting it was something of a drama, but all is resolved now. The problem I've got now is the pad has double sided contact surface on one side and on the top there is a 6mm bulge where the cables are connected, which means that if I just pup a plate on top of it then it wont sit flat. I was wondering how others resolved this issue, Iby bgkdavis - Delta Machines
Re: Individual layers slanted? - 8 years ago
IT could be that your calibration is correcting the first layer, yet the error accumulates as you increase in height First check that each tower is displacing properly, its best to do this with digital calipers. Start by moving to XY=0 and Z position so you can measure the position of each axis from a fixed position with your calipers at their shortest, write down these measurements now move aby bgkdavis - Delta Machines
Re: Mini Kossel keeps printing mirrored x axis images. - 8 years ago
The easiest way to tell if your motors are correct is to do a joy in +X and +Y When you do a jog +X the effector should move from left to right, when you do a +Y jog the axis moves towards the rear If it doesn't move in the correct direction then correct your machines wiring, if it does then correct your slicer settingsby bgkdavis - Delta Machines

Re: Mini Kossel keeps printing mirrored x axis images. - 8 years ago
when you flip both x and Y then you will still l get a mirrored part, all you have done is a 180 degree rotation, because a mirror image of a mirror image is just the original image. jut flip 1 axis and see what you getby bgkdavis - Delta Machines
Re: 220V ac Heated Bed - 8 years ago
QuoteGaou the wires isn't what i am worrying about as i can protect them with a flexible plastic tube. Are you sure? Is the tube specifically rated for insulating AC cabling (ie conduit)? Will you have adequate separation between the AC power cables and the DC signal cables to prevent inducted noise?by bgkdavis - General Mendel Topics
Re: Why Spindle driven Delta's are more precise than Belt Driven - 8 years ago
Quoteevandene Kuhling & Kuhling know how to avoid using gearboxes because of cost and the always under-estimated gearbox efficiency and ever increasing backlash. When someone can play with the lead-screw pitch, there is no reason for adding costs for a gearbox. Worm-Wormwheel gearboxes have an efficiency from 45% to 65% (expensive ones) because of the high internal friction. Planetary gearboby bgkdavis - Delta Machines
Re: Why Spindle driven Delta's are more precise than Belt Driven - 8 years ago
Quoteevandene Kuhling & Kuhling is using a RADDS controler with 1/128 micro stepper driver in their DELTA printer able to run super high frequencies. The pitch of the lead screws is about 20 mm (close to an inch), no need for a gearbox. NEMA 23 steppers will do the job. Gear drives are not only about torque you can also use them to finesse steps per mm and speedby bgkdavis - Delta Machines

Re: 220V ac Heated Bed - 8 years ago
You need a SSR (solid state relay), this will isolate the 220v heating circuit from the LV circuit on the Duet. You will need to configure your duet for on/off control, and when you wire up the SSR and heat bed make sure you don't cut corner, good quality connections and good insulation are required.by bgkdavis - General Mendel Topics

Re: Maybe an alternate source for carbon rods... - 8 years ago
Quotefrankvdh What do the arrows weigh? It seems to me that a 2mm wall thickness is overkill, and maybe increases weight unnecessarily, and therefore reduces print quality? 2mm wall thickness would be overkill but OD 7mm and ID 5mm is only 1mm wall thickness the actual weight of arrows is the other part of the complex relationship between length stiffnesss and bow power, reducing weight is impoby bgkdavis - Delta Machines
Re: Print skewed to the right as Z goes up - 8 years ago
two possible causes 1) lost motion due to slippage 2) orthogonal error you can test for 1 by starting your printer and doing a normal calibration and then mark where the nozzle touches the bed and the carraige positions when at XYZ=0, if you can measure the carriage positions accurately. Then, run a program, doesnt have to use filament, just run the program for a couple of hours After the prby bgkdavis - Delta Machines
Re: Maybe an alternate source for carbon rods... - 8 years ago
Be careful with arrow shafts there are MANY different flavors, at the cheapest end you do get simple parallel aluminium/fibreglass/carbon shafts, but as you go up in sophistication you get features like aluminium cores, barreled ODs and tapered cores Arrows are generally sold by length and stiffness, and there is a complex relationship between these factors and the power of the bow, ultimately,by bgkdavis - Delta Machines
Re: Why Spindle driven Delta's are more precise than Belt Driven - 8 years ago
QuoteDjDemonD Here's a leadscrew driven large delta. Looks nice and they are using a direct drive extruder on the effector. But I am not sure it's going to be very fast. You know looking at the pitch of those screws, then I reckon they can get some good speed out of that delta, however, whats driving those screws? are they driven directly?, is there a gear drive?, are they using stepper motorby bgkdavis - Delta Machines
Re: Why Spindle driven Delta's are more precise than Belt Driven - 8 years ago
-Quotesungod3k I had some talks with people and got inspired to look for servomotors and to keep compatibility high a converter to take the stepper signal and transform in to pwm for the servomotors. You cant just convert Stepper pulses to PWM,that's not how servo drives work. The difference between a motor/stepper motor and servo drive is a motor you just send a speed (voltage, or PWM signal),by bgkdavis - Delta Machines
Re: Printing problems - 8 years ago
Those marks are telling your something, they are rubbing, you need to identify what they are rubbing on and fix it. The arms are probably OK for now, but you should definitely look at making a set of carbon arms, the acrylic arms break.by bgkdavis - Fisher
Re: NEED HELP my 3d printer isn't working - 8 years ago
Nothing wrong with Bowden, you may get more stringing than with a direct, but good retraction settings on the slicer should help that.by bgkdavis - General Mendel Topics
Re: NEED HELP my 3d printer isn't working - 8 years ago
Normally bowden is fine, I run two deltas and a Mendel (well its now a Prusa) all with Bowdens, and 0.4mm nozzle should be an issue either. One thing I have learnt with printers is you can waste a lot of good time and even lose the will to live when using a crappy hot end, and by far the best performing hot end I now have is the E3D V6, and its magnitudes better than the Chinese E3D clone that mby bgkdavis - General Mendel Topics
