Re: Firmware uploads - avrdude.conf issues - 14 years ago
point taken with the Mac, that is why i try everything twice, once on the Mac and the second time on Ubuntu. For the sake of £15 I think I will order another cable ..... given the amount of time I (and you!) have put into this problem. At least that way I can eliminate that as a source of the problem before I find a machine from somewhere with Windows installed.by mattuwattu - Controllers
Re: Firmware uploads - avrdude.conf issues - 14 years ago
when trying to upload I get: avrdude: stk500_recv(): programmer is not responding I too find it strange that I can fully operate my machine (i.e. send a gcode and it uses it) and could in theory print if the extruder was improved, but i can't upload the darn firmware!!by mattuwattu - Controllers
Re: Firmware uploads - avrdude.conf issues - 14 years ago
An alternative cable / chip feels like a favorite at the moment. I'll tweak the settings you suggest to see if that has any effect. I have just fired up ReplicatorG (which I've never had much sucess with) and although I can connect to the Mendel, if i jog an axis, it moves but then the software freezes withe the following error: [21:59:56] DEBUG:LineNr set [21:59:56] Unknown: DEBUG:LineNr setby mattuwattu - Controllers

The VCP serial drivers from the FTDI site i installed on the Mac contains the following notes: FTDIUSBSerialDriver ReadMe FTDIUSBSerialDriver is an implementation of a serial driver for FTDI USB devices on Mac OS X. It supports FT8U232AM, FT8U245AM, FT232BM, FT245BM, FT2232, FT232R, FT245R, FT2232H, FT4232H and FT232H devices.

Re: Firmware uploads - avrdude.conf issues - 14 years ago
I tried to dig out the receipt / spec for the USB TTL board but I cannot find it. The details shown on the chip are: 101 B92 FT232 I've been on the FTDI site before to download drivers. I am wondering if I may have downloaded drivers FT232H, B or R ..... I cannot be certain.by mattuwattu - Controllers

Firmware uploads - avrdude.conf issues - 14 years ago
Continuing from my other recent post, I have lost enjoyed 2 days of my life trying to upload the latest firmware to my motherboard! Any advice would be greatly appreciated.

Re: Is this a good sign or bad sign? Problems talking to machine - 14 years ago
Mattieu, Sounds like we are at similar point in our RepRap development! Just to close out my experience of this, it is exactly the same as yours .... software incompatiblity. It is a minefield and not for the feint hearted or none techies like me! So much so, that I have spent 2 WHOLE DAYS trying to flash the software .... using 3 different computers!

Re: Extruder board not driving stepper - 14 years ago
For good practice i wanted to share what happened to close out the problems i described in this thread. I sat down this weekend to do some testing described by Noobman but before i started making cables i tried the software. What i have is a set of gen 3 boards with firmware pre installed. As much as i have tried i am unable to update the firmware. I therefore decided to downgrade the RepRap hoby mattuwattu - Controllers

Re: Trimensional (3D scanner) + RepRap = Wow! - 14 years ago

Extruder board Gen 3 - 14 years ago
Hi world, Think i may have fried my extruder board trying to getting it to work and am trying to locate a replacement. I purchased a full kit off a chap on ebay (jaworowy) and have emailed them to see if I can purchase a replacement. Anyone know of other sources for one? I spotted techzone at $45 but the shipping is almost $30! Taby mattuwattu - Wanted
Re: Extruder board not driving stepper - 14 years ago
The explanation is perfect for a true noob like me, thanks! I see from your picture that you still have an extruder board being used for the thermistor and nozzle and if i'm working this out correctly, those signals go to the MB via the RS485. With this i've now learnt that SCL/SCA is telling the stepper about the step and direction which is your case is going to a separate board. Hence I guessby mattuwattu - Controllers

Re: Extruder board not driving stepper - 14 years ago
Hi Noobman Thanks for your input, greatly appreciated There is a distinct possibility that I may have fried a chip as the pot will have been cranked up beyond 50% at some point during my desperation to bring it to life. Is there an easy way to confirm that I have done damage to either of these chips .... diagnosic tools limited to a cheap multimeter.

Re: Extruder board not driving stepper - 14 years ago
I've confirmed it is not the stepper motor by driving it off the z axis board. I thought I spotted somewhere that you can test the extruder board by connecting it to one of the 10 pin connectors for the x, y or z of the motherboard. I can't find this anywhere! Any tips?

Hi all, I'm almost there, on the home straight with a nicely moving Reprap in the three axes. Thanks for everyones help so far. I'm stuck good and proper now with the extruder.

Re: Any suggestions for Cad program for newbie? - 14 years ago
Hi, The free CAD software offerings can be a minefield from what I have seen. I've been trained with commercial packages such as AutoCAD, Pro-Engineer etc and I find it pretty easy to pickup most CAD packages. However, I find the free ones can be a bit heavy going, partly because they aren't always that intuitive. For anyone that is new to CAD altogether this could be even more frustrating.by mattuwattu - General
Re: Robitics - 14 years ago
Male I am. You sense my frustration?! I'm having a little break from the build, partly due to time shortages but mainly as i've been close to launching it, or my computers out the window! I've tried Linux, Vista and Mac OS and each has hit a dead end. Assembly, no problem, making a computer talk to a home made machine, hmmmm. Different problems on different OS's. I don't give up that easyby mattuwattu - General
