    Half round file Stu- one with fine teeth and gently and patiently- very easy to catch the edge and bend it. Here it is in the spider- I’m about to fit it to the tube- hope I didn’t mess up any measurements

    Add bs=8M when using dd bs it stands for block size - it will significantly shorten the time

    I've just done the same with mine but ran it by ssh'ing into the pi itself it returned a lot of drives but it is 128GB card astroberry@astroberry:~ $ sudo fdisk -l [sudo] password for astroberry: Disk /dev/ram0: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram1: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram2: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram3: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram4: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram5: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram6: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram7: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram8: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram9: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram10: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram11: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram12: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram13: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram14: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/ram15: 4 MiB, 4194304 bytes, 8192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/mmcblk0: 119.3 GiB, 128043712512 bytes, 250085376 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xd9b3f436 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 532479 524288 256M c W95 FAT32 (LBA) /dev/mmcblk0p2 532480 250085375 249552896 119G 83 Linux Disk /dev/zram0: 64 MiB, 67108864 bytes, 16384 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/zram1: 64 MiB, 67108864 bytes, 16384 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/zram2: 64 MiB, 67108864 bytes, 16384 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/zram3: 64 MiB, 67108864 bytes, 16384 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes astroberry@astroberry:~ $

    Here's probably best: https://github.com/WiringPi/WiringPi/releases It looks as though Gordon is no longer developing WiringPi, so I imagine the github site will be the primary source now. James

    Wow. There's a blast from the past. Back in the day Gordon Henderson and I used to hang around some of the same mailing lists (where "the day" was twenty years ago or more). James

    I have a fuller scopes 6inch newtonium in my shed my very first decent telescope with b class mirror now unused, brings back memories of some very enjoyable nights viewing

    Starting the year with a widefield narrow band rig with 135mm f2.5 Asahi Super Takumar Lens as used on vintage SLR film cameras such as the Pentax Spotmatic. These are superb quality lenses even at full aperture and all my imaging has been with full aperture. Camera - ZWO ASI 1600MM-Cool with ZWO EFW and Astrodon 3nm filters. Rig mounted on EQ8 and without guiding at first. Capture with RPi 3 running INDI firmware and saved in Linux Mint desktop indoors running KStars/Ekos.

    That's pretty much how my D-Bot is. The wheels are on diagonally opposite corners. With a heavy bed it's best to use 1mm pitch screws to avoid 'back-driving' when power is removed or z motor(s) de-energised. That's assuming 1 motor per screw. If just 1 motor with screws driven by belt/pulley arrangement then steeper screws may be ok.
