Re: SAM4S MINI board - 4 years ago
QuoteI don’t think a CAN interface is available on SAM4S Correct. The SAM4E used in Duet 2 does support CAN, but not CAN-FD.by dc42 - Experimental and Hobby
Re: Hotend Temperature dropping - 4 years ago
This is why we implanted feedforward heater control in RepRapFirmware.This temperature plot shows the effect of turning the print cooling fan on at about time 18, and off again at time 106. To reduce the amount of temperature drop, use a silicone sock on the heater block, and make sure the air is directed at the print not the nozzle or heater block.by dc42 - Delta Machines
Re: Scara Firmware Setup Confusion - 4 years ago
Thanks for pointing out the error in that paragraph. I will correct it. Further down in that page under "Homing files", it says: QuoteFor each of the proximal and distal joints, you should have a homing switch either at the maximum limit (maximum anticlockwise angle as seen from above), or at the minimum limit (maximum clockwise angle). In your M574 command in config.g, for the proximal point uby dc42 - Polar Machines, SCARA, Robot Arms

Have you considered using RepRapFirmware instead of Marlin?by dc42 - Polar Machines, SCARA, Robot Arms
Re: Kossel Delta xxl build project HELP - 4 years ago
Do you lubricate the magballs? I apply a little silicone grease every few months. The magballs on my printer have lasted years and show no sign of wear.by dc42 - Delta Machines
Upgraded Ormerod for sale, complete or in parts - 4 years ago
Due to lack of space I am selling my Ormerod 1. It has many upgrades: - Dual extrusion - Duet Maestro electronics (makes the stepper drivers much quieter, drives dual extruders without an expansion board) - PanelDue - Dual nozzle hot end board - Aluminium arm - Aluminium bed plate - Dual spring-loaded extruders - Enclosed LED power supply My preference would be for the purchaser to collect theby dc42 - Ormerod
Re: RepRapFirmware 2.04 and 3.0beta12 released - 4 years ago
Most likely you have a weak PSU or a bad VIN connection, so that every time you tried to move the motor, the VIN voltage dropped below the minimum. The Trinamic drivers don't work below about 11V. You can compile RRF with HAS_VOLTAGE_MONITOR disabled.by dc42 - Firmware - mainstream and related support
Re: TMC5160 Overheating and missing steps - 4 years ago
Do you actually need bigger motors? Might turning the current down be a solution? I don't know of any separate TMC5160 driver modules not in stepstick format other than the Trinamic evaluation board. Perhaps someone makes one in Bigfoot format.by dc42 - General
Re: Voltage regulator problem - 4 years ago
We're telling you to buy a modern controller board that is not Arduino-based and is 24V compatible. Preferably a Duet, but I'm biased - see my signature.by dc42 - General
Re: TMC5160 Overheating and missing steps - 4 years ago
Nema 23 steppers are not that big, and properly designed , mounted and heatsinked TMC5160 drivers with their external mosfets can easily handle more than 3A. But not stepstick-format drivers. Get yourself a better controller that is designed for high current motors. Duet 3 will drive Nema 34 motors at up to 4.5A RMS, 6.3A peak.by dc42 - General

Re: Homemade single arm SCARA，How to setup the software - 4 years ago
SCARA printers normally use regular Cartesian Gcode. The firmware takes care of mapping the kinematics.by dc42 - Polar Machines, SCARA, Robot Arms
Re: Kossel Mini Auto Calibrate not working - 4 years ago
There are reasons why T3P3 switched to Duet electronics and RepRapFirmware for their version 3 Mini Kossel kit! I did the original conversion of a version 2 kit to Duet for them. It was my first experience of a Delta printer. It was when I realised how difficult it was to calibrate a delta printer whose towers were not quite at 120 degree intervals that I added least squares delta auto calibratiby dc42 - Delta Machines
Re: DUET2 uses IR to automatically level the problem - 4 years ago
The usual reason for this is that the trigger height hasn't been set correctly (Z parameter ni the G31 command). See . You will get a faster response to your questions if you post at .by dc42 - Duet
Re: Ormerod 1 firmware update to 1.26 - 4 years ago
Use the online configurator at reprapfirmware.org to generate the SD card configuration files. The web files are included in the release on github.by dc42 - Ormerod
Re: Do not send a file starting with a number from Simply3D! - 4 years ago
That's one of the reasons that we normally put filenames and other string parameters in double quotes. But it's optional, for backwards compatibility. A space character after M32 would also work.by dc42 - Duet
Re: Consistent Horizonal lines on the prints of a Delta printer - 4 years ago
The trick to printing small objects in PLA is to use lots of fan cooling and either print more than one at a time or reduce the print speed. Most slicers have a Minimum Layer Time parameter to slow down printing of small objects. Try increasing it.by dc42 - Delta Machines
Re: Filament measuring thingy - 4 years ago
Yes they do. We have used two different types of sensor in our laser filament monitors. Our distributors still have some of the newer sort, e.g. . Code is on github. Unfortunately you have to sign an NDA to get the datasheet for the sensor. PS the datasheet for one of the sensors (PAT9125) is now on the web.by dc42 - General
Re: Filament measuring thingy - 4 years ago
QuoteECJ @leadinglights This laser sensor must have a small array of receivers and then the variation in the angle of the received beam to be translated as movement. But I don't think can measure speed and direction. It has a square image sensor that measures amount and direction of movement in two dimensions. Speed can be inferred from the amount of movement over time.by dc42 - General
Re: Filament measuring thingy - 4 years ago
I agree that you need to measure movement to detect extrusion issues. However, it's important to measure direction as well as movement. Otherwise, the reverse movements caused by retraction and pressure advance will cause extra movement to be recorded. Laser filament monitors work great with some types of filament but not at all with other types. We (Duet3D) used to make and sell laser filamentby dc42 - General

Re: Is Marlin 2.xx strictly for 32 bit controllers? - 4 years ago
Quotedlc60 What I really want is a 32 bit board/firmware combo that allows a config file rather than a re-compile, can network and can set the stepper currents with an M command instead of a screwdriver. But I think that I am just dreaming, right? I don't normally post on this forum, but I think I should point out that there are versions of RepRapFirmware for LPC and STM based 32-bit boards noby dc42 - Firmware - Marlin
Re: Hictop Controllers - 4 years ago
Isn't there a version of Marlin that supports more than one SD card? The SS pin of an SPI interface is only a dedicated pin when the SPI interface is operating in slave mode. In master mode, you can normally use any pins you like as the CS pins.by dc42 - Controllers
Re: What is the name of this cartesian / hbot hybrid kinematics? - 4 years ago
It's commonly called MarkForged kinematics. It's supported by the standard builds of RepRapFirmware, along with every other kinematics for which the movement of every axis is a linear function of the motion of the motors.by dc42 - Mechanics
Re: Board with LPC1768 and five tmc2209 - 4 years ago
There's a port of RepRapFirmware for STM processors now. The 64K RAM of the LPC processors is rather limiting for RepRapFirmware, and also for Smootheware I understand if you want to include both networking and some other features such as least squares delta calibration.by dc42 - Experimental and Hobby
