Re: Motor direction problem - 6 years ago
OK, I have the machine working and have done a few test cuts. I have found that the cuts are mirrored to the CAD file and have no idea on how to change that on the machine. I can mirror the CAD file, but that is not the right way to do things.by regpye - CNC Routers, Mills, and Hybrid RepRapping
Re: Motor direction problem - 6 years ago
Solved the problem, I found the error. (My error) I re-flashed the board with GRBL and after taking the wiring apart and testing one motor at a time with UGS I found that I had mixed up the direction wires for the motors. I had used white wire for the direction on all motors and coloured wires for the step wires (blue, green, yellow) It was easy to get the white wires mixed and I found the problby regpye - CNC Routers, Mills, and Hybrid RepRapping
Re: Motor direction problem - 6 years ago
I have taken some screen shots of the settings of the limits,. Inputs 2 shows what happens if I invert the polarity, the software is aware of a problem and marks the buttons in red. The homing screen shot shows that I have assigned nothing.by regpye - CNC Routers, Mills, and Hybrid RepRapping
Re: Motor direction problem - 6 years ago
Yes I have tried sending M119, but it seems that is not a command that EstlCAM knows. I get no response when I enter that. At the bottom of the screen there is a band that appears if anything is wrong and nothing is appearing. This band is in orange colour and has text displaying any error found at anytime, like comm port not found, etc. I have attached the list of commands available.by regpye - CNC Routers, Mills, and Hybrid RepRapping
Re: Motor direction problem - 6 years ago
Thanks Viktor, I have no homing switches and non are assigned in the firmware either. Homing is not activated. The firmware controller doesn't show any limits being activated either. I have reversed the direction within the firmware and the motors go the other way as expected, but still only move in one direction. The firmware is EstlCAM so maybe not many know about this (it looks really great)by regpye - CNC Routers, Mills, and Hybrid RepRapping
Motor direction problem - 6 years ago
I have just built a small CNC milling machine and am having a strange problem. I am using a genuine Arduino Uno that is driving 3x TB6560 stepper drivers that are controlling NEMA 17 steppers. The firmware is EstlCAM and I have it setup without any limit switches or probe at this stage, I just wanted to get the motors driving correctly and the stepping sorted. The distances are all correct and thby regpye - CNC Routers, Mills, and Hybrid RepRapping
Help with nano and GRBL - 6 years ago
I have a EleksMaker® ManaSE 2 controller board on a home built laser engraver. The board has a Arduino nano and has been programmed with GRBL 1.1f The board has only drivers for the motors and a laser module connection. It is working fine, but I wanted to add a couple of extra controls for pause and resume, but the board doesn't have any connections for those. It also doesn't have and limit switby regpye - Laser Cutter Working Group
Re: I need help please - 7 years ago
Big Tree were of very little help and they still have not fixed the faulty photo that is on their website and is also used in many sales sites. The motor drivers are upside down and that will cause them to blow and also destroy the board. I managed to find a few more photos showing the connections, but still not a three wire connection like the two TTL boards I have.by regpye - Laser Cutter Working Group
Re: I need help please - 7 years ago
Some news Viktor, Although not fully resolved I seem to be getting somewhere. The attached file shows that the servo has PWM and I connected a multimeter between the signal line and ground and then ran a file (just using software, no hardware connected yet) and the reading was zero before the engraving started and went up to just under 5 volts during the engraving stage. I am running GRBL 1.1f aby regpye - Laser Cutter Working Group
Re: I need help please - 7 years ago
Thanks Viktor, I have sent a request for information to them. A little worrying though, the photo of the board on their website shows the motor drivers inserted upside down. Also the printed information is lacking as well. See if I get a reply back from them.by regpye - Laser Cutter Working Group
I need help please - 7 years ago
I have bought another CNC shield recently, goes by the CNC Shield ver 2.7 name. The board has www.lubandiy.com printed on one corner. There are 8 optical isolators on the board for the limit switches and a socket for a Nano. Also there is a heavy duty hexfet near the laser connections. I am not able to find out much about this board, even though I have asked the seller and even a few other sellerby regpye - Laser Cutter Working Group
Re: Microswitch lever woes; two levers broken on my Funbot - 8 years ago
I had similar problems and changed my setup to use long button tactile switches. You need to reverse the logic in the firmware. The tactile worked so good, I now use them for the Z probe too.Very accurate, cheap and small size.by regpye - Smart_Rap
Re: Marlin 1.1.0 RC3 z servo doesn't move - 8 years ago
Tried out with 16 point probing and all is well. Guess the bed is a long way out to start with, at least 2mm from the readings shown on the screen while probing. Prints nicely now. One thing I found that needs looking at in the firmware is the LCD controller menu is not all working as it should. When selecting the nozzle temp to increase or decrease it, it jumps to "flow" and then does nothing.by regpye - Firmware - Marlin
Re: Marlin 1.1.0 RC3 z servo doesn't move - 8 years ago
Thanks for the suggestion Roxy. Yes I have it going now with the servo. I changed to a different RAMPS board selection a few times until I found the one that works. Still having some issues with the leveling though. It all works fine except that at the far front and the far back the bed is too low. The bed is pretty flat using a straight edge to test. I am now using 16 probe positions to see if tby regpye - Firmware - Marlin
Re: Marlin 1.1.0 RC3 z servo doesn't move - 8 years ago
I am also having the same problem. Tried all the above fixes, but alas no servo working yet. Works fine with an earlier version of Marlin, but I only have 3 point probing with the early version. Managed to do some prints by manually moving the servo down and up again, adding a slow Z lift so I could move the probe up before starting the print. Marlin doesn't seem to have a pause command that Iby regpye - Firmware - Marlin
Re: Blue tape in Adelaide - 9 years ago
It is worth a try, I can't see why it wouldn't work. Costs almost nothing and easy to do.by regpye - Australia, Melbourne RUG
Re: Blue tape in Adelaide - 9 years ago
Why don't you use a heated bed with PLA and forget about the blue tape (expensive and not very good) Use sugar with water. Heat it up in the microwave so that it becomes like thin honey and spread a little over the glass plate or bed with a bit of spit. The spit stops the sugar from beading. Heat the bed to 60C and print. Let the bed cool down or remove the glass and add another one to keep printby regpye - Australia, Melbourne RUG

Quoteldanut I haven't done but I can do it so we can have a better picture. My tests involved printing a lot and see if I need to recalibrate the Z offset after few prints as it happened before. I didn't have to recalibrate the Z offset at all. Whats the best way to do repeatability tests? Just do few times G29 and see the values from console?

Re: New "old" SmartRap Build - 9 years ago
Quoteprpickett Adding a heated bed to the printer currently. Also working on modifying the carriages for Reg's bushings. I seem to remember reading that they worked better if you left them connected so I need to move the mounts closer. May also try printing 10mm bushings for the Z axis since I have 10mm rod. That would allow me to use the current z rods for the x-axis and increase my build area.by regpye - Smart_Rap

Re: Unclog PLA from hotend with MEK - 9 years ago
Quotercjoseb Thanks for the info, Reg. It's really, really appreciated. I will check the temp while the fan is running during a print job. Right now, it's set to auto so it comes on after the first layer. I do have Kapton tape on it. By the way, what do you have your PLA feed rate per minute set at? I hope all is well in Australia.
