Found the solution.by methesoul - CoreXY Machines
My print bed of Corexy Printer(Hypercube evolution) starts at (70,100,0) but the homing is always at (0,0,0), If I home everything at 0, the sensor doesnot touch the z-axis print bed. I tried the following: #define X_MIN_POS -70 #define Y_MIN_POS -100 #define Z_MIN_POS 0 I know above code helps when I actually start printing. But how can I do homing at (70,100,0). May be first go to X:0 and tby methesoul - CoreXY Machines
Hi thanks for the reply guys. As i said before, it was the fault of the ramps. I used the new one it is working perfectly. On both sides the pulley are of same tooth (20 tooth pulley).by methesoul - CoreXY Machines
I had a new ramps as a spare. I replace the ramps and it started working correctly. The old was somehow defekt. I scavenged it from my old 3d printer. It was working perfectly with my old i3 prusa but on corexy it didnot. Butby methesoul - CoreXY Machines
@dc42 Hi, thanks for the reply. You can see the configuration.h file that both of the x and y steps/mm are 100. And on both stepper motor I use same stepper driver A4988. On both of the driver the jumpers wire are plugged. Is there any where I should be looking at?by methesoul - CoreXY Machines
After some debuging I found out that x stepper motor is rotating faster than y stepper motor. Any body knows why could it be so?by methesoul - CoreXY Machines
Here is a video where I explain the problem.by methesoul - CoreXY Machines
So today i finished assembling the corexy printer(Hypercube evolution) and all the electronics. I am using ramps 1.4. Corexy is activated in marlin. But when i only move x-axis then y-axis moved with it. I thought the problem lies in the tension of the belt. But it is not too tight and not too sloopy. So, it's not the porblem. The frame is rock solid with 30x30 extrusion. What did you guys do toby methesoul - CoreXY Machines
I print on glass. I I decided to buy 4mm aluminium as print bed and buy a new inductive sensor. I hope it helps.by methesoul - General
I made a custom prusa i3 and added Capacitive sensor for Auto bed leveling. If I heat my print bed before priting, the z-offset just changes each and every time. Especially when printing Ngen my print bed goes to 70 to 80 degree. And if I want to print the second print z-offset changes upto 1 mm. But if I print without heating the print bed, it prints the perfect 1st layer without any problem eacby methesoul - General
My recommendation will be to use a buck converter and an external MOSFET. Use 24V power supply and use buck converter to step down to 12V and power the Ramps. After that use external Mosfet to power the print bed. The easiest solution.by methesoul - RAMPS Electronics
Waiting for 10 minutes for my Print Bed to be heated each and every time before priting is just driving me crazy. Now I want to upgrade my rig to 24 V. The first step would generally be making ramps compatible with 24V. Buy the new components for Ramps 1.4 that are rated for 24 volts. Then 2 Step would be taking the old components from the ramps board and third step would be to solder the new 24Vby methesoul - RAMPS Electronics
