Re: Is my electronics broken? - 11 years ago
First time I just removed the stepper driver that the accident happened on. Still I couldn't connect. Then I removed RAMPS, and tried to connect, and failed. So is my Arduino having a problem? When it's physically connected to the computer, the LED on Arduino is on though.by jpan - General
Is my electronics broken? - 11 years ago
It's a long story. I was trying to solve my printing problem described in this post. The printer was connected to the computer then and the power is on. I was adjusting the current of my y-axis motor, and I accidentally touched something with the screwdriver. Then the driver of the motor sparkled in an instant. I didn't realized that it's a problem until I checked my computer after all those thinby jpan - General

Re: Please help me solve this - 11 years ago
I think "steps/mm" are both 80 In the last two pictures, the walls of the object should be straight. In the first two picture, they are actually parts of a dog so you could imagine...by jpan - Printing
Re: Please help me solve this - 11 years ago
I don't think that's a problem...I have a 80mm fan heading towards the bed, always on because connected to the PSU. The object themselves did not move as I observed.. Strange aha?by jpan - Printing
Re: Is flexible coupler helpful? - 11 years ago
Thanks for reply! but now I do't think it's a problem with z-axis check this post to see my prints please..by jpan - General

Please help me solve this - 11 years ago
Here are some print that my machine did these days. I do not think it's z-wobble caused by the threaded rods (although I thought so and nearly bought aluminum couplers) after finding out that it's only twisted in the direction of y-axis. And the distances between the "waves" don't match the pitch of my threaded rod. pic token along x-axis.(only it's not on the print bed) token along the sameby jpan - Printing
Re: Help to better my prints - 11 years ago
Thanks guys, I'm going to try tighten all screws and nuts again tonight and see what will happen. (in my impression there are indeed some nuts that are a little loose) If that won't work the I'll try other means.by jpan - General
Re: Is flexible coupler helpful? - 11 years ago
Thanks a lot. I got a lot of suggestions from the forum and I'll try them one by one.by jpan - General
Re: Help to better my prints - 11 years ago
You'll be satisfied with your print after seeing my poor print quanlity.... I am running Mendel and experiencing terrible z wobble.by jpan - General
Re: Is flexible coupler helpful? - 11 years ago
So what I should do now instead of buying a aluminum coupler is to tighten all the nuts and screws on my machine that could affect z linear rod and try again, correct? I tried tube+ plastic coupler this morning and it was no good. Also, should I tighten the bearing on the linear rod even more? Sounds like that's what I should do...by jpan - General
Why is an acme rod good? - 11 years ago
I heard that to use acme threaded rod can solve z-wobble. It doesn't make any sense to me. Can someone explain to me why is an acme rod good? Thanks.by jpan - General
Is flexible coupler helpful? - 11 years ago
I have been annoyed by z- wobble that happens on my Prusa Mendel. I plan to get two aluminium flexible coupler. Are they any good? I need some suggestion. I tried that z constraInts but they are not helpful. Thanks.by jpan - General
[US] PRUSA MENDEL I2 Assembled - 11 years ago
Fully fuctional. used. - 80mm fan (using it right now and works great.) Heat bed (never used since the power supply cannot actually drive it.) Power supply- not able to drive the heat bed but working great otherwise. I don't like the smell of ABS when it's heated so I got a small one.

Re: Connect two fans in series? - 11 years ago
Sounds good! Should I still double the max speed to let them work faster?by jpan - General
What is this? - 11 years ago
I got this thing from the package in which my prusa mendel was sent. The seller said he included spear part and I found some hardware, printed parts, and this thing. Can anybody tell me what is this? My guess is some kind of glue. Haven't try it out as glue yet.by jpan - General
Re: Connect two fans in series? - 11 years ago
That might work.. I'll try that out. What about just double "max fan speed" on my slicer. Will that work? My guess is still the 80mm one would be slower, but 40mm will be at the normal speed.by jpan - General
Connect two fans in series? - 11 years ago
I just got a 80mm fan and a 40mm fan online. I plan to use the 80mm one to cool off the print and 40mm one to cool off RAMPS. I checked and saw a small driver that sells more than $10 which seems to me too expensive. I am thinking maybe to connect the two fans in series would work, by which I mean connect one of the fans' (-)to the other fan's (+), and connect the first fan's (+) and the secondby jpan - General
Re: How to Send G-code to RAMPS 1.4 - 11 years ago
So, can I actually send m92 code and m500 save to set my machine? m503 didn't let the computer display the printer's setting, am I still able to send g code?by jpan - RAMPS Electronics

Hi lazzymonk I'm so sorry. I was a little bit annoyed then.. Now the problem's solved. Thanks for reply!by jpan - General

It worked fine before... I tightened the screw where it's connected with the board.by jpan - General
Re: How to Send G-code to RAMPS 1.4 - 11 years ago
OK, I don't think in my firmware it's allowed. So how can I read that? Thanksby jpan - RAMPS Electronics
M501 To RAMPS And Not Responded - 11 years ago
Hi guys I am using repetiter-host and printrun sometimes to operate my Mendel i2. Unfortunately, when I wanted to see my parameters from EEPROM using gcode m501, it didn't respond. Neither repetiter nor printrun worked. The motors moved all right so the RAMPS probably has received the code. Why? It DID return the numbers with my old printrboard... Thanks.by jpan - General
